Hi Jeremiah
 
** Confirmed fixed :) Thanks **
 
You might want to look at reverse_graph.hpp as it worked around the problem using:
 
    typename boost::graph_property_type<base_type>::type& operator[](graph_bundle_t)
    { return get_property(*this); }
    typename boost::graph_property_type<base_type>::type const& operator[](graph_bundle_t) const
    { return get_property(*this); }

I adapted this fix approach for my local copy of filtered_graph.hpp like so:
 
    typename Graph::graph_bundled& operator[](graph_bundle_t)
    { return const_cast<Graph&>(this->m_g)[boost::graph_bundle]; }
    typename Graph::graph_bundled const& operator[](graph_bundle_t) const
    { return this->m_g[boost::graph_bundle]; }

But your fix is general so the code in reverse_graph.hpp is most likely redundant now - I've chucked my local patch away.
 
Thanks again, Tony
