There is an open merge request for messagelib: https://invent.kde.org/pim/messagelib/-/merge_requests/100 which I would love to have fixed.
I am hitting this crash nearly daily. If you cannot reproduce this I can give you my pubring.kbx which is large enough to make this issue easily reproducible even on very fast computers.
@dvratil I am assigning this directly to you even though that is not the usual workflow.
Absolutely, I'll prioritize looking at this.
I think I can easilly generate a large-enough keyring locally :-)
Hi Dan,
the crash is back, both ingo and me are experiencing it on 23.08 with opensuse tumbleweed. Since reporting it with drkonqi somehow did not work for me here is a backtrace from a decrypt then switch, but I can very reliably reproduce this:
Application: Kontact (kontact), signal: Segmentation fault

[Inferior 1 (process 17097) detached]OK, so after debugging the issue and finally digging into the code I realized that I don't see the fix I did the first time....it turned out I committed the fix to release/23.04 branch but forgot to merge it into master and as such the change did not make it to 23.08 - which is probably why it seemingly "came back" after you upgraded. I've cherry-picked the fix to release/23.08 branch and merged it to master.
Sorry about this.
Since 23.08.2 the crash is gone again as expected. Thanks. Btw. do you know which was the first version that had this crash? I am a bit worried that our fellow debian stable users in the office might be affected with the next debian upgrade. Since we use signed / encrypted mails a lot. :)
