This simple query on the sparql endpoint http://lod.openlinksw.com/sparql:

SELECT * WHERE {
    ?s a <http://dbpedia.org/ontology/Film>
}
ORDER BY ?s
LIMIT 5
OFFSET 1

returns 4 results instead of 5, because of the offset. It works as 
expected on http://dbpedia.org/sparql.

If I remove the ORDER BY clause, it seems it works, but the SPARQL 
specification [1] says:
"Using LIMIT and OFFSET to select different subsets of the query 
solutions will not be useful unless the order is made predictable by 
using ORDER BY."
