Sorry if it was unclear, but that issue has been fixed in both Asterisk 1.4 and 
in trunk. There hasn't been a 1.4 release made yet which has the fix, but it 
will be in the upcoming 1.4.22 release. If you are using a subversion checkout 
of version 1.4, then you can update to any revision after 132790. Hopefully 
you'll see that the spirals work correctly.
