-- Information about the crash:
- What I was doing when the application crashed:
I left the laptop overnight doing nothing really.
As I don't have to login again to resume activity and leave the blank screen mode, I just pressed the ctrl key and this crash report was there.

-- Backtrace:
Application: KDE Dæmon (kded4), signal: Segmentation fault
