            Bug ID: 350988
           Summary: KDE Control Module and System Settings crashing when
                    visiting Window Decorations page after installing a
                    new window decoration
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: patrick at bistasolutions.com

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I installed a decoration, can't remember which one, and when I went back to the
select screen, it crashed. Now it crashes every time and I can't change my
window decorations.
If I try to access from settings, it says System Settings crashed. If I right
click a window bar, go to More Actions, and select Window Manager Settings, it
will say KDE Control Manager crashed.
I'm running this on Virtual Box 5, Windows 10 host.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
