Application: plasma-discover (5.14.0)

Qt Version: 5.11.2
Frameworks Version: 5.50.0
Operating System: Linux 4.18.12-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I clicked on "Applications button", and Discovery crashed immediately. Reproduced the issue three or four times in a row, tried to reboot, reproduced the issue several more times in a row, seemed like it happens always, until I opened this window to write information about the bug. While this windows is opened, Discovery works perfectly.

The crash can be reproduced every time.

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