Yes -- edges from a node to itself.

Why are you using mutate_graph?  That is specific to the Graphviz reader. 
If you are writing a graph algorithm, you can use clear_vertex and 
remove_vertex directly.  See if that solves the problem.  Also, are you 
sure the entry in bgl_nodes[node] is valid?  Your backtrace seems to 
suggest that it is a null pointer.
