"We're rewriting the whole app to fix a pretty serious bug that's been around for months, and please hold on a few more months" is probably the worst possible response.

IMHO this is really a "drop what you're doing and fix it" type of bug, even if it affects only a small portion of all users because it's such a critical high-impact bug, and any fix really shouldn't have to involve a complete rewrite.
