Application: systemsettings5 (5.12.3)

Qt Version: 5.10.0
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
- What I was doing when the application crashed:
Opened settings app. Search for "power". Double click to highlight power then backspace to erase the word 'power' from the search bar. Started typing in 'network' and it crashed. Repeatable 100% of the time.

The crash can be reproduced every time.

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