Sentry Crash Report:

Description Unknown 2016-10-03 11:29:52 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-31-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
I wanted to launch an application via typing its name in baloo, then it crashed.
Obviously there are duplicates for this bug, however I can't link them together with the assistant - after linking the report with an earlier one I'm no longer able to continue sending the report

The crash can be reproduced sometimes.

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