Application: systemsettings5 (5.12.3)

Qt Version: 5.9.1
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:
I was changing the keyboard layouts, I then started typing to test one of the layouts and it crashed.

- Unusual behavior I noticed:
Earlier when moving a window from one desktop to the other (clicked in the windows's bar and dragged to the other desktop) the system froze for 15 seconds, I don't know if that can be related.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
