OK, I think I have fixed this. A patch is up at http://trac.sagemath.org/sage_trac/ticket/4060 awaiting review.
I am cross-posting this to sage-devel to hopefully attract a reviewer. In the meantime you could patch your own source if you'd like. If you aren't comfortable doing that, you could grab www.d.umn.edu/~mhampton/polyhedra.py and copy it into your sage directory at $SAGE_ROOT/devel/sage-main/sage/geometry/polyhedra.py, and then rebuild with sage -b.
