Why do you want pies with all zero fractions? What would that accomplish?

You should be doing something like:

   g = Graph()
   v1 = g.add_vertex()
   v2 = g.add_vertex()
   e = g.add_edge(v1, v2)

   pv1 = g.new_vertex_property("vector<double>", val=(.2, .8))
   graph_draw(g, vertex_shape="pie", vertex_pie_fractions=pv1)

But I agree it should not crash if the input is invalid. I'll fix this behavior.

Best,
Tiago
