Application: plasma-discover (5.13.4)

Qt Version: 5.11.1
Frameworks Version: 5.48.0
Operating System: Linux 4.15.0-29-generic x86_64
Distribution: KDE neon User Edition 5.13

-- Information about the crash:
- What I was doing when the application crashed:
I clicked the button "Update" in the system tray and then the crash happened.
This behavior is reoccurring every time I click the “Update” button but I think it could change, when I log off or reboot the computer.

The crash can be reproduced every time.

-- Backtrace:
Application: Entdecken (plasma-discover), signal: Aborted
