Ensure that Triplestore.query() returns the same type for all backends.
For queries returning literals, it seems that the rdflib backend in current implementation returns a list of tuples of strings while the sparqlwrapper backend returns a list of tuples of literals objects.
According to the interface file strings should be returned, but it seems that it is more sensible to return literals.
Update the documentation and ensure that the backends respects it.
