yep, I'm sure. it stops working for me exactly at that revision. I've also
narrowed it down a bit more, by reverting each of the modified files from the
broken revision to their state at the working revision, and the problem seems
to occur due to some small changes in server/trace.c, server/protocol.def, and
server/mapping.c.

It seems to have something to do with these "fixed access checks"
