Application that crashed: plasma-desktop Version of the application: 0.3 KDE Version: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090624)) Qt Version: 4.5.1 Operating System: Linux 2.6.30-ARCH i686 What I was doing when the application crashed: During normal use, kwin effects were deactivated for performance reasons. When I tried to turn the kwin effects back on (via Ctrl+shift+F12), plasma crashed. This crash seems to be reproducable. -- Backtrace: Application: Espace de travail Plasma (kdeinit4), signal: Segmentation fault [Current thread is 0 (LWP 2749)] Thread 2 (Thread 0xa81c5b70 (LWP
