- What I was doing when the application crashed:
When i mouse over an application on the taskbar plasmashell crashes. I tried disabling thumbnails but i didnt help.

I transfered the system from non-virtualized (with nvidia-drivers) to virtualized (everything was rebuilt)
The crashes only occured in the virtual enviroment.
