To debug this you need to run mutt like this:

GPGME_DEBUG=9:gpgme.trace: mutt

The trace file will be pretty verbose but contains everything GPGME sees from
the engine.

Unfortunately I'm unable to test this properly, because the patches can't be
applied properly to 1.8.0 (I need to add them to the package).

Are they sending ASCII armored files (those with "-----BEGIN PGP MESSAGE-----")
of binary data?

They might have used the -t (--textmode) option and removed that.

But more likely is that this is one of the usual CR,LF problems. For example
when using FTP, and sending binary data, it is important to switch to binary
mode first. WIthout looking at the data it is hard to help.

FYI this is:
Skip tests if GnuPG is too old.
Use 'gpg-agent --allow-loopback-pinentry' if applicable.

Yes please.

Shall I look into this?

So this is about the new Python binding.
I would suggest not to build tye python support on systems with the old 2.0.24.
Note that 2.0 will reach EOL in 9 months.

Okay. So the actual cause is that we print data for a key (usage, expire, and
possible more) which we should not do. That data comes from self-signatures and
those can't be verified because we have a time warp. That should be the same as
with invalid self-signatures - what do we do in that case?

merge_keys_and_selfsig is called, but because of the clock skew no self
signature is considered and hence the expiredate is not initialized.

Fixed with commit 69c521d.
You can reconfigure your server. Thanks.

What are the reasons that expredate is not valid?
merge_keys_and_selfsig() not called for sure, Anything else?

It would appear I was wrong. The localhost address should not have been in the
/etc/resolv.conf. I have removed it and the standard-resolver option and it is
working. I have tried this several times.

I marking this as resolved since I think the issue is fixed. If this is not the
case, please reopen.

I'm marking this as resolved since I think is fixed. Please reopen if this is

This should be fixed in b1106b4 . The problem had to do with an incorrect
assumption that a key with policy 'ask' necessarily had at least one conflict.
This assumption may not hold if --tofu-default-policy is set to ask.
Thankfully, the assertion caught this.

Fixed with commit 69c521d.
You can reconfigure your server. Thanks.

There is no easy fix. We see the key usage as SCEA because pk->pupkey_usage ==
0 means 'default capabilities', and pk->expiredate == 0 means 'does not expire'.

Fixing this means being able to mark these fields as not valid, either by
initializing to a special value, or by having a separate bit to store the validity.

The former approach means taking away one more value and making it magical. It
requires a special 'not valid' value for every field, and the code has to be
changed to recognize that special value.

Using a separate bit is more general, so I went for that. Setting and testing
that bit is best done with introducing accessors. Asserting the valid bit in
the getters notifies us where to explicitly test for the validity.

Knowing where the problems are does not help if we have no way to know whether
the value in question is valid or not. Therefore, I don't see how to "lift" a
fix from the prototype.

For example, the prototype produces this crash:

% gpg --faked-system-time $(date --date "2016-07-01" +%s) -k foo@example.org
gpg: WARNING: running with faked system time: 2016-06-30 22:00:00
gpg: please do a --check-trustdb
gpg: key F35FB3E372211AFC was created 1 day in the future (time warp or clock
problem)
gpg: key F35FB3E372211AFC was created 1 day in the future (time warp or clock
problem)
gpg: Ohhhh jeeee: Assertion "(pk)->flags.valid_expiredate" in print_key_line
failed (../../g10/keylist.c:1861)

This is in print_key_line, I don't see how to fix this without being able to
tell whether the expiration time is valid or not.

Fixed in 38c955599f7c6c20faeec57d8e1df7d2c0eeba18.

Thanks for testing.

What is this Apache thing ;-). Frankly, I don't have one running and it would
be easier if you can remove it from testkolab.

What is this Apache thing ;-). Frankly, I don't have one running and it would
be easier if you can remove it from testkolab. The current Windows versions
should not have the problem anyway because warning alerts are skipped in ntbtls.
For gnutls I have a fix ready.

[I'm doing s@://@: / /@g so that roundup does not complain about this message
having too many links.]

So I did that. There are two problems:

1/ We advertise URLs of the form 'https: / /git.gnupg.org/foo.git', but this URL
contains only the name of the repository as the path. In boa, I need to specify
a non-empty path in the ScriptAlias directive for the path to CGIs, and then the
script itself also needs a non-empty name. Neither pound nor boa seem to have
path-rewriting functionality, so I don't see how we can serve a git repository
using the 'git-http-backend' CGI this way (w/o patching boa that is).

I decided to be pragmatic about it (at least for the moment) and go for URLs of
the form 'https: / /git.gnupg.org/g/it/foo.git', so I can use 'ScriptAlias /g
...', and use 'it' for the script name. However:

2/ Something is fishy with the TLS setup:

% git clone https: / /git.gnupg.org/g/it/ntbtls.git
Cloning into 'ntbtls'...
fatal: unable to access 'https: / /git.gnupg.org/g/it/ntbtls.git/': GnuTLS recv

Yes, this fixed the segfault.

Would you be so kind to test the attached patch?

(I'm operating on a hunch. Also, I'm not happy with that feature I introduced,
so I'm going to remove it one way or another. But if this was the cause of the
troubles, I'd add a remark in the commit message.)

Thomas: Is there any way how I can reproduce this now that you changed the

Yeah I broke that by fixing GnuPG to output Console Encoding. Kleo uses Qt
::fromLocal8Bit which expects the GUI CP.

Messy stuff, need to figure out how to get the ACP through Qt or the QT Name of
the console codepage for conversion. This not only here but everywhere where
Kleo shows GnuPG's console output. There are also some bugs about this at
bugs.kde.org.

Just running gpgscm crashes with segfault. Is this backtrace sufficient or do
you need me to investigate further?

I was able to reproduce it again. Maybe this bug depends on which keyserver in
the pool answers. The error is the same for Tor and non-Tor connections.

Thomas: Is there any way how I can reproduce this now that you changed the
configuration of testkolab?

Fixed in de3838372ae3cdecbd83eea2c53c8e2656d93052.

Fixed in a98459d3f4ec3d196fb0adb0e90dadf40abc8c81.

Can you be more specific?

Thanks for reporting this. I can reproduce it and will hopefully have a good
fix soon.

I don't know why, it is not repdroducible anymore.

Neal, this is still not fixed in 2.1.19.

We have seen this today also in another Kleoptra warning box. The text was not
localized but the error description (from gpg-error) had a broken Umlaut.

Yes, please do. Look at trithemius so see how to run several boa instances.
You really need to give the binary another name.

I looked into this. Pound is configured to relay these requests to
127.0.0.2:80, but no backend listens there. git http-backend can serve these
requests, is a cgi program and thus needs a webserver to run.

https://git-scm.com/docs/git-http-backend

I believe we could setup another instance of boa for the purpose of running it.

Werner, if you agree to that plan I could give it a shot.

Andre?

Yup! Fix works. Thanks, Justus.

Fixed in a98459d3f4ec3d196fb0adb0e90dadf40abc8c81.

Thanks for helping us diagnose this issue. Finally I understood the problem and
was able to reproduce it. Please keep filing bugs :)

voilà: https://gist.github.com/ilovezfs/7979ace5e07e08fbb63155fd78c70d38

I just pushed c7833eca38fdb8d9ba7b59438ea87d651b8bf7ba that will help us
diagnose the problem. Would you be so kind to apply it and rebuild your package?

Done.

Thank you.
I have removed the hint about the login problems.

Please give Bernhard and me a head-up (outside this issue) as soon as you know
which authentication method/providers you will support.

I can confirm that I can login again.

@justus: Thanks for the quick fix!
