Application: kwin (4.5.00 (KDE 4.5.0))
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
I wanted to move Amarok from on desktop to another using the Desktop grid (expose). At the same time I was doing some web development with Chrome and Firefox open, apache and mysql turned on, Kmail idle. The problem is not resource related, i had the same problem with just amarok and kmail started. 
- Custom settings of the application:
I removed most of the desktop effects because i have an older pc with old graphic cards. Animation speed is set to very fast, no effect for desktop switching and box switch, present windows, desktop grid, dialog parent, shadow, logout, logi, higlight window are the only desktop effects turned on. I have direct rendering enabled, nearest texture filter and Texture From Pixmap Opengl mode.

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