-- Information about the crash:
That's what made Plasma crash. The Panel then became mostly black(ish), but when I chose another resolution, and then back again, the Panel had it's proper colors again. Then I added the Task Manager widget again where it belongs and everything is OK now.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
