New crash information added by DrKonqi
kmail (5.22.0 (22.12.0)) using Qt 5.15.7
This was one of many crashes I got today trying to read the same email several times in a row. So I suppose the bug is now at least partially reproducible.

This is one of the latest crashes. However, I then ran "akonadictl fsck" and "akonadictl vacuum", and immediately afterwards I was finally able to read the emails that were triggering the crash without any visible issue.

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. This is after a recent KDE frameworks update in OpenSuse Tumbleweed.

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 155711 [details]

Just adding a new backtrace to show that the bug still occurs, and it still happens consistently when opening an email before PGP signature verification has finished.

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.

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).
(I guess I'm just going to keep adding these until somebody says otherwise.)
