Application: krunner (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.7.0-rc1+ x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
after a reboot following library updates, I used alt-F2 to start icewaesel and krunner crashed and restarted. The Crash Reporting Assistant also stuck on looking for duplicate bug reports until I hit the x icon to stop it.

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".
