{code}
This is caused by the following malformed markup from dbpedia:
{code}
dbr:Trento geo:geometry "POINT(11.116666793823
46.066665649414)"^^virtrdf:Geometry ;
dbp:mayor "Alessandro Andreatta"^^rdf:langString ;
dbp:imageFlag "Flag of Trento.png"^^rdf:langString .
{code}
I propose that, for string literals of datatype "langString" with no language
tag, we should simply fall back to type "string".
