It's definitely showing up in Debian Testing, I just checked that. It
is visible in GNOME Software and has all the data when I run
`appstreamcli get vlc.desktop --details` too.
(the only difference here might be that I am running GNOME Software
git master, but that really shouldn't have an impact).

Jup, this issue is preventing VLC from showing up in the results. It
likely happens due to Ubuntu's Contents file being not up-to-date,
which the old dep11-generator tool Ubuntu uses still relies on.

Debian looks fine - no error means the data is included, hints are
just informations on how to improve data.

The long-term solution for this problem is to use appstream-generator,
the same tool Debian uses, which is a rewrite of the old tool Ubuntu
is still using. Iain Lane is working on that, and I hope this will
become ready in the Yakkety cycle.
A short-term fix will be having someone (Laney) reprocess the vlc
package and checking that Ubuntu's Contents.gz file is up-to-date.
