If you have python 2.4 in your infrastructure, I've tagged a very
minor update to 0.7 that includes just this fix.
(It contains no other changes)
Folks should be aware that *usually* if you want to get newer modules
and drop them in your installation directory, you can do so -- it just
makes communicating what version of Ansible you are using fairly
impossible 
This is for those that don't want to do that.
