Bug 353057

Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-28-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:

Plasma crashes after moving window to the screen border.
In options "behavior - screen borders":
change the desktop when the mouse moving over the edge of the screen: оnly when moving windows
(sorry for bad translate)

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
