Description MartinV 2015-08-06 20:46:02 UTC
When moving a Window to another Workspace (that means: drag&drop, changing the workspace when the mouse pointer reaches the screen edge), KWin crashes and shows the "Problem report"-window.
This only happens with compositing enabled.



Reproducible: Always

Steps to Reproduce:
1. Terminal: kwin_x11 --replace
2. Grab Terminal-Window and move to egde of screen to switch workspace


Actual Results:  
1. kwin crashes
2. crash report assistent appears
3. kwin restarts automatically
4. window is on new workspace

Expected Results:  
window appears on new workspace without a crash :)

System: Tanglu (Debian 8-based) 
Desktop: XFCE 4.10 with KWin instead of xfwm4. 
Kernel: 4.0.0-2-686-pae. 
lspci -nnk:  00:02.0 VGA compatible controller [0300]: 
Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07)
	Subsystem: Hewlett-Packard Company Device [103c:30dd]
	Kernel driver in use: i915

kwin-dbg and qtbase5-dbg are installed, but the crash report assistent is still missing them.

Terminal-Output of kwin--replace until crash: http://pastebin.com/W9sY0FWM
