reporting an error for the rdf validator

Hello,

I was using the RDF validator (https://www.w3.org/RDF/Validator/) with
the example RDF code and I noticed that tool throws an error when
attempting to generate a graph.

I've attached a screen shot of the validator forms prior to submission
and a screen shot of the error message post submission.

The RDF Validator is a great tool, hopefully it is still supported and
can be fixed.

Thank You,
Robert
