Application: systemsettings (1.0)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
System Settings Login Screen
- Unusual behavior I noticed:
I ran from console. 
This message appears when the crash happens:
QSocketNotifier: Invalid socket 11 and type 'Read', disabling...

This crashes when run as sudo as well (above is from running as my user)
however, when run as sudo:
QSocketNotifier: Invalid socket 10 and type 'Read', disabling...


I have two users on this computer, they both crash.

The crash can be reproduced every time.

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