Summary:                    Python API one-liner segfaults
Description: 
~]$ python -c "import RDF; print RDF.SPARQLQuery('SELECT * WHERE { ?s ?p ?o }
LIMIT 1').execute(RDF.Model(RDF.Storage(storage_name='uri',
name='http://test.data.fm/abc', options_string=''))).to_string()"
Segmentation fault
Program received signal SIGSEGV, Segmentation fault.
0x0000003210217494 in librdf_model_storage_find_statements (model=0x6ba130,
statement=0x6e95c0) at rdf_model_storage.c:268
268   return librdf_storage_find_statements(context->storage, statement);

Additional Information: 
<dajobe> presbrey: I get that crash too
<dajobe> seems to be in the python bindings, it works from C
<dajobe>  rdfproc -s uri http://test.data.fm/abc query sparql - 'SELECT * WHERE
{ ?s ?p ?o } LIMIT 1'
<dajobe> looks like python destroyed the model object before the query ran
<dajobe> since there was only 1 use
