Application: krunner (5.8.0)

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.8.1-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
I don't know if it's possible to reproduce it every time, but KRunner crashes from time to time after typing program name and pressing enter to launch it. After plasma reloads, I am able to run KRunner again, and launch the application succesfully.

The crash can be reproduced sometimes.

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