            Bug ID: 345508
           Summary: KDE System Settings crash when changing window
                    decoration every time.
           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: lsd at atheist.com

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.18.7-1 x86_64
Distribution: "KaOS"

-- Information about the crash:
- What I was doing when the application crashed: Changing the Window
Decorations.

- Unusual behavior I noticed: Application crashes only when I scroll down
(mouse wheel/arrow key) and before selecting other theme. 

- Custom settings of the application: Using 'evolvere light theme'. Tested same
with other 3rd party themes. Did not try 'breeze' theme. 8+ themes installed.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
