Application: kontact (5.9.3) Qt Version: 5.11.3 Frameworks Version: 5.54.0 Operating System: Linux 4.19.0-2-amd64 x86_64 Distribution: Debian GNU/Linux buster/sid -- Information about the crash: Open KMail (in Kontact), it crashes. If it does not, it will do so shortly after. Open a few E-Mails and there you go. I suspect that the crash might be due to graphics handling in the nouveau driver. Experienced the same issue on the nvidia legacy 390 binary driver. Sometimes just before the crash I can see the message pane flashing in red color. This is not the latest KMail but the one packaged with Debian/Buster. I'd like to file a bug with Debian referencing this one on kde.org. They might need to backport an existing fix. The crash can be reproduced every time. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

https://bugs.kde.org/show_bug.cgi?id=404052 might be related, though I do not need to kick off any filters to make the crash happen. Opening E-Mail is enough, it will usually crash after a few mails to be opened.
Just as Martin in 404052, I missed debug syms. Got them installed now and trying to get another backtrace.

Crash is in nouveau_dri.so OpenGL driver. Please report this issue directly to nouveau developers. See also https://nouveau.freedesktop.org/wiki/Bugs/
(In reply to Christoph Feck from comment #5) > Crash is in nouveau_dri.so OpenGL driver. > > Please report this issue directly to nouveau developers. See also > https://nouveau.freedesktop.org/wiki/Bugs/ This looks right. It is a known bug upstream, see https://bugreports.qt.io/browse/QTBUG-41242 https://bugs.freedesktop.org/show_bug.cgi?id=91632 Building against OpenGL ES (instead of GLX) seems to evade the issue. Sadly, setting vblank_mode=0 __GL_SYNC_TO_VBLANK=0 does not fix the issue for me.
(In reply to Christian Hilberg from comment #6) > [...] > > Sadly, setting > > vblank_mode=0 __GL_SYNC_TO_VBLANK=0 > > does not fix the issue for me. It does, however, if using the NVidia binary blob (390xx for me).
