Description Nikolai 2019-09-18 06:49:03 UTC

Application: plasma-discover (5.14.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 5.2.0-2-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid

-- Information about the crash:
- What I was doing when the application crashed:
	Open discover
	Start search "text editor"
- Unusual behavior I noticed:
	At first search goes normally, but after a while (it is possible when results are found) the window hangs up and the application comes to the end with an error

The crash can be reproduced every time.

-- Backtrace:
Application: Центр программ Discover (plasma-discover), signal: Segmentation fault
