Created attachment 154581 [details] New crash information added by DrKonqi kmail (5.22.0 (22.12.0)) using Qt 5.15.7 So the crashes still happen, and it's really annoying. The backtrace is a little different, but the behaviour I encounter is the same, so I'm assuming this is still the same bug.

OK, I think I've determined the precise cause of the crashes. They consistently happen when: - clicking away from an Email, - that is signed with a PGP key, - *before* KMail has finished verifying the signature. If I wait for signature verification to finish, KMail does not crash.

Created attachment 160257 [details] New crash information I hadn't been able to reproduce the bug recently (maybe for a few weeks, but I'm not exactly sure), so I got adventurous and stopped waiting for the first PGP signature to be verified before looking at other emails. But then it happened again this week, see attached crash report. The reproducer remains the same: launch KMail, select a PGP signed email to read, then select a different email to read before the first one's PGP signature has finished verifying, and KMail should crash.
Created attachment 161434 [details] New crash information added by DrKonqi kmail (5.24.0 (23.08.0)) using Qt 5.15.10 Same reproducer as usual: click away from GPG signed email before the signature was verified (this time coincidentally to an email that was *also* GPG signed, in case that might make a difference).
