Just found it in the docs. Sorry for my blindeness, but I thought of the 
filtered_graph in terms of a regular graph (so no special num_vertices 
behaviour). I learned the hard way :-(. Maybe this exception of 
num_vertices should be mentioned in the description text of 
filtered_graph along with the reasons you lined out.
