Application: systemsettings5 (5.12.0)

Qt Version: 5.10.0
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

Selected "Application Style"
Moved by Tab to focus the Widget Style combo box.
Moved by Down key up to Windows 1.3 style (gtk2 lies below).
Move by Down key once and the app crashes.

Didn't try this second time. gtk2 can be also selected by mouse and nothing wrong happens.

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