Application: krunner (5.11.5)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.14.15-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I opened krunner using Alt+F2 and was in the middle of typing 'firefox' into the prompt, maybe at 4th or 5th character, when the krunnner crashed.

The crash can be reproduced every time.

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