Operating System: Linux 3.18.0-13-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
sometimes my kwin ation "dubbleclick on window boarder minimize window" dont work anymore. kwin starts just the drag action. in this case i need to restart kwin with
kwin_x11 --replace
this works fine but sometimes kwin crashes

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
