-- Information about the crash:
Note that I hit this after amdgpu started acting up (which it does once a week
or so) where rendering becomes extremely slow. I restarted, logged into sddm,
then Firefox + Signal was opened with session restore. plasmashell was already
crashed and I got the crash report pop up. Same happens on subsequent reboots.
The crash can be reproduced every time.
