-- Information about the crash:
Thinkpad with docking station, doesn't happen always, but lately it occurs pretty consistently. Basically I lose my panel if I attach the laptop to the dock or detach from it, and more rarely afterr sleep/power save. Probably in general I'd say whenever the display layout is changed.

- Unusual behavior I noticed:

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
