Bug 413772

Application: systemsettings5 (5.17.2)

Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.3.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:

I had changed something in the Display and Monitor module. When I closed the program I got the message it crashed and I could file a bugreport. This does also happens with changes in others modules. I did not notice it when I did not make a change.

The crash can be reproduced sometimes.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
