Hi Martynas,
more specifically the ";charset=utf-8" seems to be a problem. If you
leave it out it seems to work fine:
curl -H "Accept: application/rdf+xml, application/n-quads, text/csv"
http://dbpedia.org/resource/Copenhagen -L
Do you really still need this? UTF-8 seems to be ubiquitous.
I didn't check q=0.x or similar. There seems to be something with the ";".

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;
