Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Opened settings manager and then went to session management. Updated some options and then tried to open the Login Window options. 

At this point the Settings Manager crashed.

The crash can be reproduced some of the time.
