Application: systemsettings (1.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.11-99.fc12.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was installing some software - language packs - nothing special, but had a dependency problem. I accidentally tried to install an i686 and an x86_64 version of the same programme (SCIM - I think).... anyway - I went back, correct the problem and installed without problem.

I then closed the Systems Settings window using the (X) button which is when the crash occurred.

 -- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
