Application: systemsettings (1.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.0.0-19-generic i686
Distribution: Ubuntu 11.10

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

- Second monitor attached on the VGA1 port
- System Settings > Startup and Shutdown > Service Manager
- Checked the Display Management change monitor startup service (Not Running state)

1. If I click on Start the crash is reproduced and the service still remains as Not Running
2. If I click on Apply (Not Running) the service starts normally and settings are applied correctly with service shown as Running
2a. From that point on the Start/Stop options work as expected.

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