-- Information about the crash:
Plasma Shell (and only Plasma Shell) crashes repeatedly (every couple of
seconds for a few minutes) on reboot. I can still get to a GUI, open
applications with Alt+F2, and so on. In fact, I can open Konsole and run
startplasma-wayland from there, and then it works perfectly without so much as
a message on stdout or stderr. It's only when started by sddm that it seems to
crash.
The crash can be reproduced every time.
