Can you middle click or right click and open a new tab or some other such alternate click pattern to get to the actual subscribe someone else page? Does that page work?

This is related to bug 382018 and likely a fix for one will get the other. In both cases, characters not normally used in URIs are used in usernames. I would have thought we would have prevented spaces, plus signs, etc. since usernames are used in URLs, but I should have checked to confirm rather than assuming.
