Qt Version: 5.5.1
Operating System: Linux 4.3.3-2-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
Suggested Duplicate 355882 (sorry but from GUI I couldn't send data without filing this one , some UX problem)

- What I was doing when the application crashed:
After plugging Lenovo X230 into Docking station, I issued :

$ xrandr --output DP3 --off --output DP2 --off --output DP1 --off --output HDMI3 --mode 1920x1200 --pos 0x0 --rotate left --output HDMI2 --off --output HDMI1 --off --output LVDS1 --off --output VGA1 --off

command , as usuall and then : KWin and Plasma , both crashed.

- Unusual behavior I noticed:

Normally it was turning on external monitor and turning off laptop one. Now I have both.

- Custom settings of the application:

Above command.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
