How does it end up getting called like that, do you have a test?

If I had to guess, I suppose it's possible that we end up with less
than three vertices after eliminating duplicates in
d2d_path_geometry_triangulate(). In that case though, it would make
more sense to move the vertex count check in that function after the
duplicate elimination.
