I'm afraid so. It's a nasty bug: besides a number of minor consequences, it breaks thue(), which users could rely on in publications. And breaks it in a bad way: we return incomplete answers to a difficult problem, which is impossible to check without an altenate implementation. There's no point releasing a stable version containing a known grave bug. Especially when the fix is a 2 lines patch.
