Description Vedran Ljubovic 2017-06-06 10:01:38 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-72-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

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

Started searching for an app in Application Menu widget. Plasma crashed as I typed the first four letters (keep). I don't think this is related to Baloo crash that Assistant is suggesting as duplicate, since Baloo is mentioned nowhere in my backtrace and I'm not using it.

The crash can be reproduced every time.

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