-- Information about the crash:
- What I was doing when the application crashed:
I left my computer for some time and screens went off, as expected per power
saving setup. When I came back, I moved the mouse to awake the computer, found
the lock screen as expected, input my password and once back to my desktop
plasma widgets were not visible, other windows were and the "report crash"
dialog appeared.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
