Summary: kwin_wayland sometimes crashes when connecting to
docking station

journalctl -b | grep kwin_wayland - no debug symbols
SUMMARY
***
This is something that actually didn't happen before, and I use Wayland session
since 5.24, although I previously used Arch Linux and only recently switched to
Fedora.
I use USB-C Dell WD19S docking station that is connected to 2 1080p screens and
ethernet cable. Te dock was always a little bit junky regardless to what
software I used, but with a little hiccups it works as expected (sometimes I
need to re-plug it when it fails to activate screens, my laptop freezes for few
seconds after it's connected). Since 5.24 it was also fine on kwin_wayland and
didn't cause crashes (before that it wasn't usable at all, it was crashing and
misbehaving like crazy).
The crash today happened just like it did when I last was in the office. I
resumed from suspend, unlocked it, connected the dock and then kwin_wayland
died along with everything that was running.
Sadly I don't currently have backtrace with debug symbols and the issue is not
easily reproducible - it stops happening completely when I restart the docking
station. Well, even if it's purely because of that dock it shouldn't cause the
entire compositor to crash.
I collected 2 log files from `journalctl -b`. It casually crashed now when
writing the report when I tried to check installed firmware using fwupdmgr
(yes, it is supported and the firmware is up-to-date).
Now I installed kwin-debuginfo and kwin-wayland-debuginfo packages. When the
crash will happen again, I should be able to fetch some more useful logs, I'll
come back here with it.
***
STEPS TO REPRODUCE
1. Resume laptop from sleep after some longer usage
2. Connect do Dell WD19S docking station with multiple screens
OBSERVED RESULT
kwin_wayland segfault
EXPECTED RESULT
Even when the dock connection is wanky, keep kwin_wayland working
