            Bug ID: 321514
           Summary: Custom Title Bar Button Positions Crasses Settings
    Classification: Unclassified
           Product: systemsettings
           Version: 1.0
          Platform: Debian testing
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: pughmds at cyram.org

Application: systemsettings (1.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-4-amd64 x86_64
Distribution: LMDE Cinnamon Edition

-- Information about the crash:
- What I was doing when the application crashed:
I was adding buttons and removing spaces from the titlebar buttons in System
Settings.  I was adding custom button options such as shade and keep above
windows and trying to remove the spaces between the maximise and close
application buttons.  No matter what I added or removed, the application
crashed once I clicked on OK.  

I repeated this several times trying to remove or add different buttons and
each time the application crashed.   Any application change that didn't involve
"Use custom titlebar button positions" worked fine.  Even ticking the custom
titlebar button positions and not making any changes after that caused it to
crash once the OK button was pressed.

- Custom settings of the application:
In Workspace Appearance Settings, Window Decorations, Configure Buttons, the
"use custom titlebar button positions" option was ticked.

The crash can be reproduced every time.
