Just to confirm what the backtrace tells me: were you using the desktop grid effect at the time of the crash and were you moving a window? In that case is it possible that the window closed while you moved it?

In that case is > it possible that the window closed while you moved it? Yes, I was using that effect. The chash happened after I try do group some gimp tools windows. When I did it, the windows stopped to response (they were there, but the window actions (move, clicks, etc.) didn't work anymore. I think I tryied to use grid effect at this moment, and it crashed (but I'm not sure). Now I can't remember if I closed or not gimp windows before use grid. Sorry :-) And I'm using lastest fglrx driver. The crashtrace does not make sense at all. It's crashing in kwin here: if( isUsingPresentWindows() && windowMove->isOnAllDesktops() ) and the next item in the crashtrace is QPixmap. Neither of the two methods called in the if statement access QPixmap. We have a whole bunch of strange backtraces and they all have a referrence to glib and Ubuntu. Somehow I fear there is a pattern in it... *** Bug 267562 has been marked as a duplicate of this bug. *** Git commit 0c23185cfd2b0210d58af603b94813a5473a547d by Thomas Lübking.
