Application: krunner (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.6.0-rc6+ x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
when starting iceweasel from krunner, iceweasel started but krunner crashed leaving 2 krunner processes that did not respond to alt-F2. Manually killing the 2 krunner processes and restarting krunner did work though.

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".
