-- Information about the crash:
- What I was doing when the application crashed:

I was simply switching activities with keyboard shortcuts ( next activity
shortcut ). The activity switcher sidebar appeared and i noticed that an
activity was missing. Right away plasma crashed.
When restarted, it showed all activities and didn't crashed again.

The crash does not seem to be reproducible.
