-- Information about the crash:
On a multiscreen setup, when unlocking there is occasionally a crash handler
dialog complaining about a plasma crash.
Desktop looks normal and is restored to a normal state, just the DrKonqi dialog
complaining about the crash
It's not directly after a lock or a manual lock/unlock. But usually when
leaving the machine for a while to to lock itself then coming back a few hours
later.
This behaviour has been around for more than a year since the machine was on
Debian 11 and persisted through the upgrade to 12.
There are several standard widgets running and frequent changes to primary
screen and going from 1->2->3 screens multiple times a day.
The crash can be reproduced sometimes.
