Then:
Rebooted the host into Kde desktop.
Core was generated by `/usr/bin/plasmashell --no-respawn'.

Reproduce the coredump with:
Work in the Kde Plasma desktop for some time with a small workload.

The plasmashell automatically restarted itself after this coredump, and the Kde desktop continued to function; which is good.

Other information:
If the computer screen is locked for a longer timespan, the Kde plasma desktop is unusable after re-login.
The complete screen display is black, with the exception of pre-existing Kde Konsole application windows.
To continue working, the only possibility is to reboot the computer.
The Kde Plasma desktop works as usual after the reboot.

Bye

The crash can be reproduced every time.
