Hi,
finally got some time to look into that ...
First - my assumption that the patch for STANBOL-877 got not merged
into the codebase was wrong. It is present in both 0.12.1 and trunk.
So this means that both reported errors are indeed new issues.

null means to search for literals without language tag (the null
language). This is why
FILTER(((lang(?v_1) = "en") || (lang(?v_1) = "")))
is in the SPARQL query
Finally the disambiguation-mlt engine will not work with the SPARQL
backed Enityhub Site. This is simple because SPARQL does not allow
MoreLikeThis queries. Still it does look like as if the unsupported
constraint type results in an additional '.' added to the query. This
needs to be fixed.
best
Rupert
