Description Rafal 2019-02-25 17:10:03 UTC 
Application: plasma-discover (5.15.0)

Qt Version: 5.12.0
Frameworks Version: 5.55.0
Operating System: Linux 4.20.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I have searched for audio recorder using krunner. It redirected me to audio recorder on discover and then crashed. I tried few more times and it is always crashing. Searching via searcher in discover works well.

The crash can be reproduced every time.

-- Backtrace:
Application: Odkrywca (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
