Actually, that's not what prevented FreedroidRPG 0.16 to be included in the
Gnome Software database (when fdrpg 0.16 was packaged for F23, those 2 links
were available).

IIRC, the Fedora packager changed the icon's file name, but without changing its
reference into the .desktop file (I can be wrong, but it's something like that).

In 0.16.1, released some days ago, package and icon names are now all in
lowercase, more compliant with freedesktop rules.

I'll tell the Fedora packager to no more change those files.
