That should not be the case, but you're right... something isn't as it
should be here.

Zwooop...  (That's the sound of me running off to the lab to test this
one)

So, it seems obvious to me that this is a bug.  I've posted more
information and an explanation of what I think is going wrong in the bug
tracker, as well as a proposed patch for the Asterisk 1.4 brach, trunk,
and the 1.6.0 branch.

See http://bugs.digium.com/view.php?id=12777 for more details.
