-- Information about the crash:
I've set Plasma up to automatically put the monitors to sleep after a period of
inactivity. Frequently this will result in one or more components of the Plasma
desktop crashing like this. There will typically be a period where there are no
panels visible, or the panels are frozen, before the crash handler realizes
that something has gone wrong and resets Plasma.
Curiously the crash reporter is saying that the windowing system is X11 even
though this is a Wayland system. This system also has an Nvidia card and is
using the official drivers, I'm mentioning this because I have noticed quite a
few oddities in Wayland with Nvidia cards, but I'm not sure that it is
specifically related in this case.
The crash can be reproduced sometimes.
