Application: krunner (5.9.2)

Qt Version: 5.8.0
Frameworks Version: 5.31.0
Operating System: Linux 4.9.9-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- Unusual behavior I noticed:
Every now and then krunner crashes. the app I try to launch is always different.(not app specific) 
Plasmashell however usually doesn't load when I log in the first time I either have to start it manually with "kstart plasmashell" or log out and in again, it also takes long to load. this never used to happen.

The crash can be reproduced sometimes.

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