This is not on any workboard. But I tested it with 4win-Beta-64 and the error shown in Kleopatra is now "Unusable public key".
So I'll put it on vsd33.

Saw it in a screenshot somewhere, can't find it now. I do not have a version with that commit.

As this ticket is for vsd33, the nice design tweak has to go into another ticket, it will not be backported to kf5.

When checking this out with gpg4win-Beta-64 I can reproduce case 1 (and of course 3) but not case 2:

Regarding triage: This is not widely encountered and a workaround exists

and why is the link to the bug tracker in the authors tab?
We could also discuss it the KDE Bugtracker is the best place to link to for that…

When we change the About-dialog we should change some other things there, too, not only the author information.

This is related to T6072: Kleopatra: Display "gpgconf -X"

I'd have no objections against making it less prominent.
Instead of the "Protocol" label we could then maybe add a tooltip/info to the buttons with something like "the protocol to be used".
I know, tooltips are not popular with you ;-)

Does the notepad really need to support S/MIME? People might want to use inline PGP with Kleopatra, but S/MIME???

Agree

What is wrong in your opinion?

Tested with VS-Desktop-3.2.94.2-Beta.
Works as expected on the cli.

works for VS-Desktop-3.2.94.2-Beta (Beta for VSD 3.2.4)

Test with gpg4win-Beta-50 shows the same as described in the last comment.

tested with gpg4win-Beta-50:
works as described in https://dev.gnupg.org/T6866#179915

gpg4win-Beta-50:
Columns are now displayed as expected with a fresh installation, too.

Tested with gpg4win-beta-50:
Adding a subkey works, its possible to add A, E or S subkeys with different algorithms and expiration dates.

closing this ticket as duplicate as adding and changing expiry works.
Revocation of a single subkey is not yet possible in Kleopara, though

As we now have tabs for the subkeys this task is obsolete, really. Its useful as a parent ticket though.

gpg4win 4.3.1 was with keyboxd, too. And vsd33 is only to mark that it would need to be backported for the next release (if this is a Kleopatra issue)

oh, I should have reloaded before commenting ;-)

In https://dev.gnupg.org/T7296#192032 you said you backported parts of T6666.
And the tooltips are in title case, currently, like Tobias said.
An improvement of the tooltips in this regard is not strictly necessary for the next release, though I admit it would be very nice.
But we need to add the "(except disabled ones)", which means a string change and if we are doing one change there, we should make all other changes to the tooltips in one go. Otherwise the translations would have to be done twice, too.

with gpg4win-Beta-50 on a new (not upgraded) installation I see kleopatrarc in the folder %APPDATA%\kleopatra and kleopatragroupsrc in %APPDATA%\gnupg\kleopatra. And no kleopatra files in the base directory of %LOCALAPPDATA%.

works, the Root-CA of the above example is only shown once any more. Gpg4win-Beta-50

Deletion works, tested with gpg4win-Beta-50.

works, gpg4win-Beta-50.
The focus now stays on the selected line when you open e.g. a details window and close it again.
