-- Information about the crash:
Please note: I'd be willing to try to recreate the bug with debug symbols, but
I just cannot find the debug packages for the list of files mentioned by this
crash handler.
- What I was doing when the application crashed:
Just before the crash recorded here, I was using Gnome, switched user, and
tried to start KDE desktop. It comes up and opens applications, but the
background is black and the panels are missing. More generally, after a system
reboot a couple days ago, every time I go into KDE I see what I'm seeing
now--no panels, black background. I don't typically get asked to do a bug
report.
- Unusual behavior I noticed:
I upgraded to 22.04 a couple weeks ago from 20.04, where I had no problems with
KDE panels. In 22.04, I noticed the panels were unstable. They and the
background would disappear after suspend or sometimes while I was using the
desktop. I used 'kstart5 plasmashell' to resume the panels and background,
which worked. I am using X11.
But a few days ago, I rebooted to find that the panels and background were
missing, which had not happened before. When I tried to use variations of
'kquitapp5 plasmashell && kstart5 plasmashell' to activate the panels and
background to no effect. Multiple reboots made no difference. I reinstalled
all the software related to plasma I could find, also to no effect.
I did upgrade a couple packages before the reboot after which KDE stopped
functioning properly. I could be wrong, but I think those packages were:
kde-config-sddm and bluedevil.
- Custom settings of the application:
I moved the panels around, resized them, and added a few widgets (weather
widget, widget to show all open windows, widget to minimize all). Besides the
weather widget, I don't think I'm using anything besides what I normally have
for years. The weather widget worked for a number of days before my KDE
stopped functioning properly.
The crash can be reproduced every time.
