OK, I see that and in fact it was caused by two bugs, one in C and
one in python caused by the combination of the RDF.NS in python and
the statment you happened to be querying with (not your fault).

I've fixed both of those and removed the double-free.  I tested
your program against last night's snapshot sources and it does not
crash.  However, your crashes may vary :) so give it a go!

I couldn't test on SourceForge's OpenBSD server since it was too bare
- no python and I wasn't going to build it and their OSX server is
similarly missing some python parts.
