Bad error message when installing broken flatpakref file
Download the attached flatpakref file and double click it to open in Software:
org.gnome.Epiphany.Canary.flatpakref
This flatpakref is broken, so it's expected that Software would fail to install it:
$ flatpak install --from org.gnome.Epiphany.Canary.flatpakref
error: The application org.gnome.Epiphany.Canary/x86_64/master requires the runtime org.webkit.Platform/x86_64/0.3 which was not found
However, the error message that Software presents is not good:
This error message doesn't make any sense. Something is wrong with Software's error handling.
