Okay, so the following shows the problem, right? http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=select+distinct+%3Flabel+lang%28%3Flabel%29+as+%3FlangTag%0D%0A+where+%7B+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2F31_June%3E+rdfs%3Alabel+%3Flabel+%7D&format=text%2Ftab-separated-values&timeout=30000 I am purposely using doc URIs as this helps the entire problem confirmation and resolution cycle.
