Summary:                    librdf_query_results_get_count returns 0 (before
results are iterated?)
Description: 
librdf_query_results_get_count no longer returns a correct result count
until the query_results have been manipulated in some undetermined (by me)
way.

I call librdf_query_results_get_count directly after librdf_query_execute
in mod_authz_webid to do ASK-style ACL checks and it used to work great.

I'm attaching test code, repeating the meat of it below, and pasting the N3
into "additional information"...

librdf_query_results *rdf_query_results = librdf_query_execute(rdf_query,
rdf_model);
printf("[query] %d results, sparql: %s\n",
librdf_query_results_get_count(rdf_query_results), query); // 0 results :(
printf("[results] %s\n", librdf_query_results_to_string(rdf_query_results,
NULL, NULL));
printf("[query] %d results, sparql: %s\n",
librdf_query_results_get_count(rdf_query_results), query); // 8 results
