Hmm. No suggestions for 4.6.x other than to trace the code and find
where it is calling interaction_error() -- I think it needs to return
where it doesn't now. It also needs to return a false value so that you
don't display a page.

We are not putting maintenance effort on anything but show-stoppers on
the 4.6.5 tree at this point, so it is unlikely to be fixed there. 4.7.x
takes the pragmatic approach of just stripping the non-numerics.
