Application: krunner (5.7.5)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.7.3-kern x86_64
Distribution (Platform): Gentoo Packages

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

Several times now I could observe the following.
- first use of krunner after login
- press Alt+F2 to bring up krunner
- start typing quickly and press enter (not really waiting for what it wants to show me)
- Krunner crashes.

I'm currently using Plasma 5.7.5 on Gentoo Linux with standard packages.

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
