Work around http://code.djangoproject.com/ticket/4720 - removing

the document name from the url would result in a 500 error.  This
workaround has intimate knowledge of the feed class (in particular,
that link() is the first method it calls with obj==None).
Hopefully we will remember to remove it when deploying on a django
version with this bug fixed.
