Sentry Crash Report:

Description Nate Graham 2019-04-18 13:31:14 UTC 
STEPS TO REPRODUCE
1. Don't install the Snap backend, or uninstall it
2. Open the URL "snap://gwenview"

OBSERVED RESULT
Discover shows a page saying:

Sorry...
Couldn't open snap://Gwenview

EXPECTED RESULT
A page saying something like, "Cannot display snap://Gwenview because support for Snap applications is not installed."

And then there should be a button that installs the backend when you click on it. After the backend is installed, it should attempt to re-open the original URL using the newly-installed backend.
