-- Information about the crash:
Invoking "Switch User" from Kicker and KRunner, then leaving the window open, crashes Plasma Shell. However, selecting one of its buttons causes me to see `#000000` with only my mouse, and it cannot be moved. Switching TTYs isn't possible, either.

The crash can be reproduced sometimes.
