Changes in 0.1.15 and how to use same code on stable machines

for the Debian Pure Blends tasks pages I'm using python-debian.  I frequently
used code like

    printsting = unicode(stanza[field], 'utf-8')

to handle UTF-8 encoded strings.  When using python-debian >= 0.1.15
this results in

   TypeError: decoding Unicode is not supported

exceptions which is caused by the change which is refered to in the
changelog saying:

  [ John Wright ]
  * deb822: Better support for non-ascii values.  Deb822 objects now
    always contain unicode objects instead of strings.  Use the encoding
    argument to Deb822's initializer and its iter_paragraphs class
    method if the encoding of a file you are reading in is not utf-8.
    (The dump method also takes an encoding argument, if you wish the
    output not to be utf-8-encoded.) (Closes: #495272)

While I'm really happy about the change which simplifies things I wonder
what you would suggest to run the same code on development as well as
production machines (for instance which generates the
tasks pages). is only featuring 0.1.14 and I have
no idea which code relays on the old behaviour and what might be broken
there would be a backport of the recent python-debian would be installed
on alioth.

Any hints?

Kind regards
