Description lsd 2015-03-25 11:38:53 UTC

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".

I experience the same bug.

Unfortunately the backtrace lacks debug symbols. If you are still able to reproduce it, please install debug symbols and attach a new backtrace.

Comment 8 KDE 2018-09-27 01:14:42 UTC

While I encountered this frequently when it was reported, the last few KDE version have been problem free. I'd suggest closing it, as I doubt it can be reproduced now.
