Hi,

I think I had shown this to Kingsley some time ago, but it's still not fixed :)

When presented with multiple Accept header options, DBPedia respons
with some weird Content-Location header and an empty RDF graph:

GET http://dbpedia.org/resource/Copenhagen
Accept: application/rdf+xml; charset=UTF-8,application/n-quads;
charset=UTF-8,text/rdf+n3; charset=UTF-8,application/n-triples;

charset=UTF-8,application/rdf+xml;
charset=UTF-8,application/rdf+thrift; charset=UTF-8,text/turtle;
charset=UTF-8,application/rdf+json; charset=UTF-8,text/trig;
