llyn RuntimeError: Already in store but bindings new?

I'm trying to make a picture of bwm's RDF schema for P3P,
but cwm craps out thusly:

$ python cwm.py --chatty=20 --rdf
http://lists.w3.org/Archives/Public/www-archive/2001Dec/att-0006/02-p3p-rdf-schema.xml
--n3 http://www.w3.org/2001/02pd/rdf-schema-fig.n3 --think
--base=ephemeral: --bySubject --rdf=c > p3pFig.rdf

[...]
        *** Conclude: _formula  ::  theGraph   hasNode  Resource  .
        *** Conclude: _formula  ::  theGraph   hasNode  PolicyRefs  .
        *** Conclude: _formula  ::  theGraph   hasNode       Seq  .
Concluding: Forget it, already had ???@@@@?? c->PolicyRefs
c2->PolicyResource
Already list:  [[(<http://www.w3.org/2001/02pd/rdf-schema-fig.n3#c>,
