> i open a bug report by ubuntu...
please don't. This is a known issue. Also ubuntu devs know about it - there is nothing we can do 
at the moment, except to be wait.

Ok, i do not, you can close this case, thanks !

New crash information added by DrKonqi

kwin (4.6.2 (4.6.2)) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:
I was testing some OpenGL screen savers and clicked the mouse to exit.
- Unusual behavior I noticed:

KWin crashed and the whole desktop restarted
