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.
