Application: systemsettings (1.0)
KDE Platform Version: 4.9.00
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

When I go to the System settings to change my workspace appearance theme system settings crash every time. Basically these are the settings I had from KDE 4.8.4 morphed over to 4.9 so if they are incompatible, i have no idea how to change or reset if it keeps crashing on me.

-- Backtrace:
