Sentry Crash Report:

Description Marco Schulze 2017-09-26 02:56:15 UTC 
Application: krunner (5.7.5)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-59-generic x86_64
Distribution: Ubuntu 16.10

-- Information about the crash:
- What I was doing when the application crashed:

I pressed Alt+F2 directly after logging in. I did not yet enter any character in krunner's text field -- actually krunner didn't become visible to me at all (maybe it crashed so quickly that I didn't see it).

I wanted to mark this report as a possible duplicate (not sure) of another bug (383744), but the KDE bug reporter seems to have yet another bug, here, not allowing me to link this new report to the old issue :-(

The crash can be reproduced sometimes.

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