Hi Mark :)

Thank you for being patient with an idiot :)

You are right!  I guess my experience was that would install things,
even gstreamer, but run rhythmbox from Alt-F2 so I wouldn't get the
environment of the newly installed profile, whereas if I had run from a
shell I would.  I didn't know what was going on.

What would happen if we made gst-plugins-ugly also add the same
native-search-paths?  Multiple packages can add the same paths, right?
In that case you wouldn't have to install gstreamer.
