Application: plasma-discover (5.12.0)

Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.15.1-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I tried to install some programs from standard openSUSE Tumbleweed repos and progress feature was unreliable and only some of programs I selected got installed. Few times the whole Discover interface crashed, and left PackageKit running in the background.

The crash can be reproduced sometimes.

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