-- Information about the crash:
I have some windows opened, they are grouped into one button on the taskbar.
usually it is (Dolphin or Ark)
Every time when i try to close this windows by right-clicking a taskbar button
and choose "Close" plasma will almost always crash and re-start taskbar and
widget panel
plasma also sometimes crash in the same manner when taskbar button is not a
group, but exact single window/application. But this a rare case
The crash can be reproduced sometimes.
-- Backtrace:
