I disagree: it looks like a bug to me: pure and simple. The problem is
that cnames aren't checked in check_for_local_domain() in rfc1035.c. It
looks like naptr records got missed to, but I doubt anyone his tripped
over that one!

If you're happy to run test code, (I'm running it in production) I can
have a new test release which fixes this available in an hour or so. If
you want a patch to a stable release, the fix will be trivial to backport.
