Comment(by vbraun):
I noticed that, too. I haven't gotten around to fix it because I ran into
this strange doctest failure in Sage-4.5alpha1 that worked beautifully in
sage-4.4.4:
{{{

main/sage/geometry/cone.py", line 1535:
sage: c.faces()

Andrey, since its your code maybe you'll understand what is going on.
