These bits come from external sources, and often buggy ones at that. We
should probably just compute the index and skip it if it's out of
range. Sending a mode of all zeros along to the rest of the server is
likely to cause chaos (and divide-by-zero errors).

It is nice to have separate patches anyways; one per bug. That can make
back-porting changes easier to manage.
