Bug 328794

Application: systemsettings (1.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.11.0-15-generic x86_64
Distribution: Ubuntu 12.04.3 LTS

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

When I try to open the touchpad settings whole systemsettings program crashes.
Hint: I installed xorg drivers for my nvidia geforce card with optimus technology from http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu. Maybe this combination fails?

The crash can be reproduced every time.

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