Application: krunner (5.7.4)

Qt Version: 5.7.0
Frameworks Version: 5.25.0
Operating System: Linux 4.4.29 x86_64
Distribution (Platform): Slackware Packages

-- Information about the crash:
- What I was doing when the application crashed:
 Just invoking Krunner through Alt+F2

Suddenly it stopped showing and now Alt+F2 is not operative.

The crash does not seem to be reproducible.

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