When loading a ttl via the loadData.sh script I get the following error when trying to load a blank node with white space between the brackets.

Could not load: url=file:///wdqs/wikidump-00000000
1.ttl.gz, cause=org.openrdf.rio.RDFParseException: Expected an RDF value here, found ']'

The loadData script does work correctly when I remove all white space between the brackets. Here is what the turtle looks like which causes the error:

wd:Q100301425 rdfs:label "Large Single-Handled Jar, Yale University Art Gallery, inv. 1930.655"@en ;
    wdt:P571 [ ] ;

According to the turtle docs

The [162s] ANON ::= '[' WS* ']' token allows any amount of white space and comments between []s. The single space version is used in the grammar for clarity.

Is there anyway to prevent this parse exception? I would consider it a bug.
