sorry, it crashes in the driver. There is nothing we can do about it. Feel free to report it against mesa on freedesktop.org.

As it crashed while loading the Explosion effect, I recommend to disable that one (and all other effects using shaders: e.g. blur, invert, sharpen, lookingglass)

New crash information added by DrKonqi

kwin (4.7.00 (4.7.0)) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.2

- What I was doing when the application crashed:
I was trying to enable most of the desktop effects with different video drivers offered by kubuntu by default (170 - recomended and 173) for nvidia go 7600. No succes with opengl; the same situation with xrender.
- Custom settings of the application:
???
