Bug 374295

Application: systemsettings5 (5.8.5)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.8.13-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I started systemsettings5 and went to "application style" under "appearance". Then, I loaded every sub-menu (on the left) twice or more. When going back to All settings after doing this, the application crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Impostazioni di sistema (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
