Application: systemsettings5 (5.12.0)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.15.2-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Clicking in each subsection one after the other in the shortcuts sections of system settings: Standard shortcuts, then Global shortcuts, then Web shortcuts, then Custom shortcuts. When I clicked on Custom shortcuts, having clicked previously on Web shortcuts, it crashed. I tried to find a pattern and it seems that it will crash each time you pass from web shortcuts first and then click on another category.

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