Application: systemsettings (1.0) KDE Platform Version: 4.4.1 (KDE 4.4.1) Qt Version: 4.6.2 Operating System: Linux 2.6.32.10-90.fc12.i686 i686 Distribution: "Fedora release 12 (Constantine)" -- Information about the crash: I was trying to switch on desktop effects. Desktop effects seem really unstable - they were on before I switched off my machine but when I restarted, desktop effects switched off. When I restarted, the system was also acting slowly. I tried to start system settings a few times but the cursor bounced with no response. Finally when system settings was able to start, I enabled desktop effects, it crashed. -- Backtrace: Application: System Settings (systemsettings), signal: Bus error [KCrash Handler] #6 memcpy () at
