Application: krunner (5.12.1)

Qt Version: 5.10.1
Frameworks Version: 5.43.0
Operating System: Linux 4.15.3-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

"Alt + F2", then typed "f" (and it autocompleted firefox), then Enter, then the segfault (but Firefox was opened). The backtrace is generated for this case.

But also, if I have already opened Firefox before typing it in krunner, then it crashes without pressing Enter, only typing f.

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".
