It was completely trivial to get this patch working again. I did the work while Emily watched over my shoulder. If one positive review isn't enough, then you have two! :)

Oops... ignore the patch trac_6098-reviewer.patch. Just to let people know, only the patch trac_6098-rebased.patch has been merged in sage-4.1.1-alpha0. I can't close this ticket because I don't have the privilege to do so. Sorry, folks :-(
