Sentry Crash Report:

Description Dylan 2013-05-19 02:34:39 UTC 
Application: kwin (4.10.2 "release 1")
KDE Platform Version: 4.10.2 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.4-desktop i686
Distribution: "openSUSE 12.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
In 'Configure desktop effects', I set Desktop Effects > Advanced > Compositing type to OpenGL from XRender (in an attempt to make all of the KDE effects work).

After I clicked Apply, Kwin attempted to use that setting, then crashed and restarted using its prior settings.

- Custom settings of the application:
Contents of Desktop Effects > Advanced before attempting to enable Kwin (i.e., when Kwin is completely stable):

Compositing type: XRender
Qt graphics system: Native
Keep window thumbnails: Only for Shown Windows
Scale method: Crisp
'Suspend desktop effects for fullscreen windows' is unchecked

The OpenGL Options section is greyed out since Compositing type is set to XRender.

Contents of Desktop Effects > Advanced that are changed from above when trying to enable OpenGL:

Compositing type: OpenGL
'Use OpenGL 2 Shaders' has been tried both checked and unchecked with the same results.
'Use VSync' has been tried both checked and unchecked with the same results.
'Enable color correction (experimental)' is unchecked.

- Other information that may be relevant:
I'm running this in VirtualBox v4.2.6 on an Intel Mac running OS X v10.8.3. The virtual machine has 3GB RAM, two 2.8GHz CPU cores with no execution cap, VT-x, Nested Paging, 128MB video RAM, and 3D acceleration.

The crash can be reproduced every time.

I'm sorry it crashes in the driver of the virtual device. Nothing we can do about it.
Comment 2 Thomas Lübking 2013-05-19 07:09:48 UTC 
try to disable the blur effect, resp. the "cache blur results" setting.
also (random guess): what's the output of "glxinfo -l | grep -i tex" (in the virtual machine)
