Does the Shell work normally, other than this warning?

(I *think* it will work normally without this service, except that
screencasting, screen-recording, remote desktop won't work.)

Please could you try removing that package, and installing
gir1.2-gstreamer-1.0? I think gir1.2-gstreamer-1.0 is the one you actually
need to avoid this error message, and gir1.2-clutter-gst-3.0 just works
around the issue by depending on it.

Most GNOME users will have both of those as a result of packages like
totem depending on them, so this will only happen in practice on systems
that have GNOME Shell but don't have most of the rest of GNOME, which
is presumably a description of your system.
