kloecker 2024-11-05 20:46:16 +0000 Thanks for the report! With a newer version of Kleopatra I cannot reproduce the crash anymore. I tested this with several keys. I always get just one password prompt and then an error message is displayed. It seems that canceling the password prompt is still not handled correctly, but at least it doesn't crash anymore. The remaining issue is tracked at https://dev.gnupg.org/T6091. I'll close this report as FIXED because the crash has been fixed.
