Comment 1 Justin Zobel 2022-09-30 04:37:57 UTC

Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version?

If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you!

Comment 2 Erik Quaeghebeur 2022-09-30 07:45:40 UTC

KMail crashes are hard to reproduce even if they are not resolved. In any case, I haven't come across something like this crash for a while, so I'll mark it as WORKSFORME.
