Speaking as the guy who wrote the first version of that code...

I don't think this is the right fix; the point of that code is to
remove a tuple queue from the funnel when it gets detached, which is a
correct thing to want to do.  funnel->nextqueue should always be less
than funnel->nqueues; how is that failing to be the case here?
