Description hayleyhung 2010-04-08 08:50:41 UTC
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

Comment 1 Dario Andres 2010-04-08 15:17:36 UTC
The crash is not related to the Desktop Effects but to a pixmap cache which is having some problems. This issue is being tracked at bug 231448.
