Operating System: Linux 4.16.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Discover breaks when triying to install a snap package (Visual Studio Code) On OpenSuSE Tumbleweed fully upgraded ad today. It usually breaks when installing snap packages, sometimes it doesn't ask for the root password and then breaks

The crash can be reproduced sometimes.

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