see http://paste.lisp.org/display/92767

I get answers with 

res = g.query("SELECT ?g ?s ?p ?o WHERE { GRAPH ?g { ?s ?p ?o } } ")

... but if I use "SELECT * WHERE (etc...)" it fails - ValueError: need more
than 0 values to unpack

"The SELECT form of results returns variables and their bindings directly. The 
syntax
SELECT * is an abbreviation that selects all of the variables in a query."

These issues involve bits that have been moved out of rdflib proper for now. We 
will re-open them 
or move them to rdfextas as appropriate.
