Application: krunner (5.7.3)

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.7.1-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
Whenever I try to start "Chromium", KRunner will crash after a few keystrokes, while displaying a few PIM contacts at the top of the list.

This is a duplicate of #364342, but DrKonqi has a bug that does not allow me to mark it as a duplicate (bug #355807).

The crash can be reproduced every time.

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