Comment(by gbe):
It looks like there's a bigger problem here:
{{{
sage: a=BipartiteGraph(matrix(2,2,[1,0,1,0]))
sage: a
Bipartite graph on 3 vertices
sage: a.vertices()
[0, 2, 3]
}}}
It can't be a coincidence that the missing vertex in a.vertices() is also
the vertex missing a label. Of course, this may raise the question of why
the fourth vertex is being drawn in the first place; however, I don't know
enough about how graphs are drawn to be certain of that.
