Application: kwin (4.4.5 (KDE 4.4.5))
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.37-trunk-amd64 x86_64
Distribution: Debian GNU/Linux 6.0 (n/a)

-- Information about the crash:
I was moving a window (kdevelop) from one desktop to another using the present desktop effect, and then when I clicked on the kdevelop window the zoom in, kwin crashed.

Maybe unrelated additionnal information:
When I zoomed out, kdevelop was loading itself (so there was just the splashscreen window), then I moved the splashscreen window to another desktop, and then I suppose that kdevelop was in the process of switching from the splashscreen to the main window at the instant when I clicked to zoom in.

 -- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
