Comment:
I've posted a patch trac_11358-wstein.patch that fixes the bug. The
solution is definitely much better than what was proposed 10 years ago.
You can run the attached 11358.sage to check that the exact bug cited here
doesn't happen. But better is to see the new doctests which get to the
heart of the matter.
