Application: systemsettings5 (5.17.2)

Qt Version: 5.13.2
Frameworks Version: 5.63.0
Operating System: Linux 5.3.8-arch1-1 x86_64
Distribution: Arch Linux

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

I was configuring the monitor order for making my laptop screen the secondary, and the screen 2 the primary the first time and upon selecting the 'Startup and Shutdown' catagory afterwards, is when the crash occured. I restarted the app and from the main screen selected that catogory and it crashed again. I restarted the app and did it again and that time it worked, but I had accrued 2 or 3 bug reports in the process.

The crash can be reproduced sometimes.

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