-- Information about the crash:
- What I was doing when the application crashed:
On my Laptop (Acer Extensa 5220) I pressed Fn + F5, then LVDS was deactivated and the second screen VGA (Pacard Bell maestro 220 LED, maybe you need to know) was activated (1920x1080).
I opened KRandTray to change the settings and activated LVDS again and changed VGA to1280x800 after pressing >keep settings< plasma crashed.

-- Backtrace:
Application: Plasma-Arbeitsfläche (plasma-desktop), signal: Segmentation fault
