That says give me a parse with name rss-tag-soup AND with the mime type
of RDF/XML.  That condition isn't met since the rss-tag-soup covers
multiple mime types so doesn't register itself as covering one only.
So... parser return null.  (maybe the registration should cover multiple
mime types in future, but it doesn't right now).

Fix:
parser=RDF.Parser(name='rss-tag-soup',mime_type='') 

In the python bindings 1.0.0.2 I've added a convenience class for this
which will allow parser=RDF.RSSTagSoupParser()

yeah, it really shouldn't do that.  I wonder why 'parser' isn't None?
