Bug 298447

Application: systemsettings (1.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-22-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

Launched "power management" from within "system settings" -> "Service manager".
Clicked on the "use" to enable on boot up, then clicked on "start" causing it to crash.

It would appear, enabling the service will also auto start it for you. It would also appear that the start button does not know how to handle starting a started service.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
