Application: systemsettings5 (5.17.3)

Qt Version: 5.12.5
Frameworks Version: 5.64.0
Operating System: Linux 5.3.11-200.fc30.x86_64 x86_64
Distribution: "Fedora release 30 (Thirty)"

-- Information about the crash:
- What I was doing when the application crashed:
open systemsettings
click, e.g. Plasma Style, go back, click sth else, go back, click plama style again... crash.
(same happens on window management or workspace behavior)

What works, though, is to open systemsettings, click on plasma style, close systemsettings. Then open systemsettings again, click on plasma style, and it still works

Very annyoing bug

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
