Application: systemsettings5 (plasma 5.9.0)
On X11

Qt Version: 5.8.0
Frameworks Version: 5.30.0
Operating System: Linux 4.9.8-1-MANJARO #1 SMP PREEMPT Sat Feb 4 11:59:58 UTC 2017 x86_64 GNU/Linux
Distribution: Manjaro KDE

-- Information about the crash:
- What I was doing when the application crashed:
go to systemsetings5 > workspace > desktpop behavior > (click on all the options available there) > go back to previous screen. And here is where the application crashes.

Same bug can be reproduced by doing the same on "application style".

The crash can always be reproduced if I follow those instructions.

-- Terminal output:
