            Bug ID: 301746
          Severity: crash
           Version: 1.0
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: System Settings>Workspace Appearance Crash
    Classification: Unclassified
                OS: Linux
          Reporter: kaj at bell.net
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: systemsettings

Application: systemsettings (1.0)
KDE Platform Version: 4.8.80 (4.8.80)
Qt Version: 4.8.2
Operating System: Linux 3.4.0-5-generic x86_64
Distribution: Ubuntu quantal (development branch)

-- Information about the crash:
- What I was doing when the application crashed: clicked on workspace 
appearance in system settings when it crashed. Crashes consistently.

- Custom settings of the application: was trying out qtcurve in application
appearances , but it doesn't seem to matter what decor is used , workspce
appearance just crashes anyway.

The crash can be reproduced some of the time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
