Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: ar...@aarsen.me
Target Milestone: 1.0
Application: plasmashell (6.1.0)
(Compiled from sources)
Qt Version: 6.7.2
Frameworks Version: 6.3.0
Operating System: Linux 6.8.12-gentoo-dist-hardened x86_64

-- Information about the crash:
When the screen turns off, then on again, various KDE components crash.
Notably, Plasma, KRunner and Dr Konqi crashed. They only appear to crash if
they have displayed a screen before. I have a backtrace from KRunner as well,
and also WL_DEBUG logs at time it crashed. Will attach in a comment (sending
this through the crash handler assistant on the plasmashell process).
I've posted this in the Wayland goal room on Matrix. I've done a little
digging on the KRunner crash I mentioned above and noticed a few things. Will
post in a backtrace together with what I noticed in a comment under this bug.
The crash can be reproduced every time.
