I have reproduced this with libkleo from our gpg4win/24.05 branch and with gpg (GnuPG) 2.4.6-beta102 (HEAD of STABLE-BRANCH-2-4) and current master of gpgme and all GnuPG libraries. It took just 8 runs until a unittest failed.

gpgme logs for a failed test where the keylisting with gpgsm failed

Last time I used the Non-Sucking Service Manager to create a windows service.
This works fine when the program gracefully stops on a OS terminate signal.
But this is an additional dependency.

If the keylisting (of OpenPGP and S/MIME certificates; technically, that's two independent keylistings) fails without giving any results then it makes sense to show a error message instead of the welcome page.

I do not want to do that for 2.2.45 (T7255) because we want to do that release RSN

Is there a mechanism which can be used for this? Of course this could be done using the usual autostart feature, or we turn the server into a Windows service (ask @alexk). Start the client along with kleopatra?

Thanks for opening a bug report. This is better for our workflow.

But the DEVINFO --watch is required to trigger this hang? Kleopatra does not use this but we see simlar hangs from time to time in the current version.

This might be caused by https://git.gnupg.org/cgi-bin/gitweb.cgi?p=gpg4win-tools.git;a=commit;h=30b5736a97d884452c9ad8c713600326ee06a7c3

This is also relevant for VSD 3.3. Backport is not needed, but gpg4win/VSD needs to include current gpgme.

Yes, the fix is included in the Gpg4win 4.3.1.

Replacing gpgrt_spawn_actions_set_environ by gpgrt_spawn_actions_set_envchange is not good, as it's exported and already used.

Was the fix part of a stable release? The beta was 4.2.1b55. Stable download on https://gpg4win.de/ is 4.3.1. Am I correctly assuming, that 4.3.1 includes the fix and this issue here can be closed?

This is a super old bug report, this is likely fixed with a new version of Kleopatra, so I am closing this. If this happen again in the future, feel free to reopen this bug report.

This is no longer possible. The sign/encrypt button is disabled and an info box is displayed.

No reply for a very long time, so I am closing this ticket. This is likely fixed now. Feel free to reopen if this happen again.

No reply for a very long time, let's close this.

This report is a bit old. I just tested gpg --keyserver https://keys.openpgp.org --search-keys mail@mhammerbacher.de on my laptop and this work fine.

gpg4win 4 has been released with unicode support. Closing.

I created https://invent.kde.org/pim/kleopatra/-/merge_requests/287 for the appstream file.

This is now done and it is much simpler now
