Application: plasma-discover (5.12.4)

Qt Version: 5.9.1
Frameworks Version: 5.44.0
Operating System: Linux 4.13.0-43-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:
Discover has been telling me for weeks that I need to update the Gnome 3.26 flatpack, however it's already installed. For some reason, it won't go away in Discover as an installable update. I clicked on the Update button multiple times, which then crashed Discover.

What would be really nice here would be a way I can tell Discover to ignore this Flatpack because it is already installed.....

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
