Bug 275228

Application: systemsettings (1.0)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

I had previously just tried to set a user icon, then the tabs all disabled themselves so I had to go back to the main system settings window, and back into the login manager screen. Then I tried to setup auto-login, pressed apply, and System Settings crashed.

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