            Bug ID: 301143
          Severity: crash
           Version: 1.0
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: Touchpad settings crash in KDE 4.8.3 on Kubuntu with
                    Xorg-Edgers PPA
    Classification: Unclassified
                OS: Linux
          Reporter: bwyazel at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: systemsettings

Application: systemsettings (1.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was opening the touchpad
settings in KDE 4.8.3, and the application repetedly crashes when doing so
before the window loads.

- Custom settings of the application:
I am running Kubuntu 12.04 with the Xorg Edgers PPA installed, which provides a
newer Xorg server and newer synaptic drivers. It did not crash before this
update, and now it does, so I assume it is due to this upsate.

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