Application: kwin_x11 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
Moving VMWare Player windows (Control window, before starting a VM) from VD1 to VD2, using the Mouse, by Drag and Drop of the Windows over the screen edge. 
Crash seemed to occur when I pushed the Windows beyond the Screen Edge, and it finally initiated the Virtual Desktop Change (Cube effect)

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