      Description

      With a dataset with multiple graphs the above query should report the names of all the named graphs, in fact it returns a single row, with ?g unbound.

      The ASTGraphGroupOptimizer is responsible for these matters.

      See [1] for discussion.

      See [2,3] for related tickets.
