Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-16-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
I'm on lucid, Since fglrx is not available, X is using the open ati driver. (I guess). After installing newest X and rebooting the system, I tried to enable the desktop effects. Just when I hit the OK Button on the confirmation screen, I got the crash notification. No desktop effects are enabled now.
regards,
Hans-Peter
