Summary: Getting out edges for empty graph cause access violation.

Initial Comment:
Getting out edges for empty graph cause access 
violation, see example below:

#include <boost/graph/adjacency_list.hpp>

using namespace boost;

typedef boost::adjacency_list<boost::vecS, 
boost::vecS, boost::bidirectionalS> Graph;
typedef boost::graph_traits<Graph>::in_edge_iterator 
InEdgeIterator;
typedef boost::graph_traits<Graph>::out_edge_iterator 
OutEdgeIterator;
typedef boost::graph_traits<Graph>::vertex_descriptor 
Vertex;

int main()
{
        Graph g;
        Vertex CurrVertex =	vertex(10,	g);

        OutEdgeIterator	in_start, in_end;
        tie(in_start, in_end) =	out_edges(CurrVertex, 
g);

        return 0;
}
