Bug 409778

Application: systemsettings5 (5.16.80)

Qt Version: 5.13.0
Frameworks Version: 5.61.0
Operating System: Linux 5.1.16-1-default x86_64
Distribution: openSUSE Tumbleweed

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

Clicked on "look and feel"

Most of the items in system settings crash it no matter the type of view used, wth the exception of:
Window Management, Shorcuts, Startup and Shutdown, Search, Account Details, Online accounts, Connections, Input devices, Power management.

The crash can be reproduced every time.

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