Oh nice a new #openlinksw #virtuoso release coming! https://github.com/openlink/virtuoso-opensource/commit/5cf13cd06c131c25043c4b6525eee46455a606ca looks it will have some nice fixes and improvements.
Surprisingly, I could not find an Issue about this #DBpedia problem. Now there is one: https://github.com/dbpedia/extraction-framework/issues/820
Contrary to my initial guess of an extractor bug, further investigations made an SPARQL endpoint (#openlinksw #virtuoso) bug seem more likely.
