"Discover" does not able achieve to completely end every progress. When I installed something from "discover" -all remove and all install tasks actions except updates-
Because of that I stopped form system monitor every progress remove and installation.
Progress on %100 but it doesn't stopped himself. It prevent my action When I acted closing progress to discover. Even log out progress.

That errror didn't occour aftrer that or starting discover. But it may be relevant stability.
Just as error occoured while I am doing installing the OBS.
By the way. I'm using Kde Neon distro.

- Unusual behavior I noticed:

The crash can be reproduced every time.
