Gpg4win doesn't include libexpat anymore (since it doesn't include gpa and pinentry-gtk anymore).

We stopped maintaining GPA in favor of Kleopatra.

Finally had some time to look into this a bit more.

A simple first step would be to install pinentry-gtk only in the GPA variant.

I think this is because we install pinentry-gtk, too. So we have that GTK dependency.

I verified that manually putting the DB in WAL mode also resolved this issue, since writers don't block readers in WAL mode.

Thanks for using GPA. Unfortunately, I have to tell you that GPA development has been stopped and I can't say whether we will fix that bug any time soon. Please consider to switch to Kleopatra which is the standard key manager included in gpg4win.

Done for gpa.
Please test.

Done for pinentry.

I have reproduced the bug

A backtrace with gdb from migw-w64 results in

I did a fresh install of Gpg4win 3.1.14 and imported my standard pubkey, by using

gpg --locate-key bernhard@intevation.de

on the command line.

Sorry, I can' reproduce thus. What kind of key is causing the crash?

Which version of Gpg4win did you install, from where, and which OS version are you using? Why did you install gpg4win at a non-default location?

Fixed.

Taking: Still does not work although now --quick-set-expire is used by gpgme.

Yeah, this can be done.

Well, gpa needs to use gpgme's interface for receiving and sending keys. The use of the helper programs an old hack.

Werner: I'm assigning this to you. Because the underlying reason is a missing status from gpg. I think we should add that for 2.3 as any new status line tends to break things.

Hello,
when can we fix it?

Closing this as invalid until the info requested in the last comment is provided.

@werner This issue also applies to GPA. Looking at the edit key interface I can't see how we can handle this. Am I overlooking something or do we just loose the error information / is it not emited by gnupg?

@sapienza Can you try it with Kleopatra please and if it fails there, too please post the "Diagnostics" from Kleopatra. (See "Blocco note" in Kleopatra for the same functionality)

Did you encrypt to a key of yours? You can only decrypt if you have the matching secret key for the public key you used for encryption. The error message: "No secret key" should be obvious.

I've tested it with Gpg4win-3.1.7, too and it works for me so something must be special.

this error comes to me when I try to decrypt a message and I get this message
