Basically it's the RDF.Uri constructor that's failing. This is the 
version with the use of str() as you suggested. This however throws the 
same error. The full script was attached to my original post.

         def process_channel(self, uri):
                 print "Found channel", uri
                 try:
                         statement = RDF.Statement(RDF.Uri(str(uri)), 
self.rdftype, self.channel)
                         if self.model.contains_statement(statement) : 
return
                         model = RDF.Model(self.storage)
                         parser = RDF.Parser(name="rss-tag-soup")
                         parser.parse_into_model(model, uri);
                         if model.contains(statement):
                                 self.model.add_statement(statement)
                                 print "Added", uri
                 except Exception, e:
                         print uri, "threw an exception.", e

It was indeed of type unicode, however casting didn't solve the problem.
