            Bug ID: 328794
           Summary: Systemsettings craches when touchpad settings are
                    tried to open
    Classification: Unclassified
           Product: systemsettings
           Version: 1.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: bjoern.kasper at versanetonline.de

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
