Relative URIs in xml:base - RDF/XML parser disagreement?

There was an interoperability problem discussed in a nearby list...
  http://lists.w3.org/Archives/Public/semantic-web/2005Jul/0040.html

I can't tell if it points out a problem in the spec or not.
I'd like confirmation one way or another.

And in any case, please put the question and the answer into
the RDF test suite, at least the unofficial one...

if not the official one
