Ah, your query works!
I had just missed a '}' character in the end.
Thanks Andy, but why did my query not work. It was:
SELECT ?subject ?predicate ?object
WHERE {
?subject ?predicate ?object
}
LIMIT 25

The list does not pass attachments through.
How are you runnign the server exactly?
Ask this query:
SELECT * { { ?s ?p ?o } UNION { GRAPH ?g {?s ?p ?o } } }
and don't forget to press the "query" button (it caches results otherwise).
