Sentry Crash Report:

Description Lastique 2017-02-12 16:25:09 UTC 
Application: krunner (5.7.5)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.9.0-8.1-liquorix-amd64 x86_64
Distribution: Ubuntu 16.10

-- Information about the crash:
krunner crashed when I typed "sound" (I was trying to type soundkonverter to start the application). I had similar crashes when I was typing different things, so I don't think the particular text matters.

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
