This is fixed in version 0.1.15, by making Changelog objects iterable
(see [bug 539334][1]).  You can download the latest version from
[p.d.o][2].

Unless you have verified that a bug is not Ubuntu-specific, you should
usually use [Ubuntu's bug reporting tools][3] to file bugs against
packages in that distribution.  I believe there is a mechanism to ask
them to sync a package with Debian in order to fix bugs like this one,
but I'm not really familiar with it.

You mention wanting to get the .changes for a particular version.
Currently the Changelog/ChangeBlock class probably exposes enough
information to generate such a file, but it doesn't actually generate a
.changes file like from 'dpkg-genchanges'.  Feel free to file a wishlist
bug via reportbug.  Patches are always welcome, too. :)  If you do work
on it, it would probably be ideal if the method returned a
debian.deb822.Changes object.  Also note that .changes files can (and
often do, in Ubuntu's case) contain changes from a range of versions.

I hope you have found python-debian useful!
