Do you have a simple test case to illustrate this? I'm able to
retrieve contexts in streams on hashes storage without trouble.

I'll grant it may be a bug that the context returns NULL in this
case. However, you don't exactly need the context from the stream
because every statement returned by
librdf_model_find_statements_in_context() will by definition have a
context node == pContex. Also note that if you replace
librdf_model_find_statements_in_context() with
librdf_model_find_statements(), librdf_stream_get_context() does
return the context node.
