Application: systemsettings5 (5.12.4)

Qt Version: 5.10.1
Frameworks Version: 5.45.0
Operating System: Linux 4.16.3-1-ARCH x86_64
Distribution: "Arch Linux"

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

I oppened the settings, clicked on "Application Style", then "Widget Style", then "Fine Tuning" I then searched for "Menubar" in the search field and the software crashed right when I was typing the "b". Here's a video of it: https://giant.gfycat.com/NewWideBluewhale.webm

Another thing to note, the menubar settings are gone from that menu, I don't even know if this is normal or not.

The crash can be reproduced every time.

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