Bug 320766

Application: python2 (0.9.0)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-24-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
I had to manually strart userconfig.py because the system settings gives and error:
"The service "User Management" does not provide an interface 'KCModule" with keyword "userconfig/userconfig.py' The factory does not support creating components of the specified type.

Not sure where the mess starts but obviously deep in the bowels of my machine.

The crash can be reproduced every time.

-- Backtrace:
Application: userconfig (python2.7), signal: Segmentation fault
