This bug was fixed in the package python-debian - 0.1.16ubuntu1

---------------
python-debian (0.1.16ubuntu1) maverick; urgency=low

  [ Scott Howard ]
  * Merge from debian unstable (LP: #588714).  Remaining changes:
    - Depend on python-apt as debian_support uses it unconditionally.
    - Add .lzma as a possible extenstion for data.tar (LP: #407198)
      Note that this does not mean that reading from the .lzma part
      is supported. This is blocked on http://bugs.python.org/issue5689

  [ James Westby ]
  * Use os.path.normpath to ensure debfile tests work across python
    versions.

python-debian (0.1.16) unstable; urgency=low

  * debian_support: Be more careful in case apt_pkg is not available
    - If apt_pkg is not available, AptPkgVersion now raises
      NotImplementedError on any initialization attempt
    - test_debian_support.py now doesn't try to test AptPkgVersion if
      apt_pkg is not availble
  * test_deb822.py: Don't test gpg info if debian-keyring is not
    available (Closes: #573934)
  * Use the warnings system to report deprecation warnings
    (Closes: #573945)
  * Change examples and control file to refer to debian instead of
    debian_bundle

python-debian (0.1.15) unstable; urgency=low

  [ John Wright ]
  * deb822: Don't ignore leading newlines on field data with apt_pkg
    (Closes: #466753)
  * changelog: Consistently parse different types of inputs.  The
    previous implementation added extra newlines when given a file
    object as input, rather than the result of str.splitlines().
    (Closes: #539316)
  * deb822: Faster non-shared storage by keeping a TagFile object
    around for each Deb822 object yielded

  [ Stefano Zacchiroli ]
  * make debian_support.Version hashable, patch from Piotr Ożarowski
    (Closes: #543223)

  [ Filippo Giunchedi ]
  * changelog: add iterator over changelog blocks (Closes: #539334)
  * changelog: split tests into tests/test_changelog.py for consistency

  [ John Wright ]
  * deb822: Use the apt_pkg.TagFile class instead of apt_pkg.ParseTagFile()
    (Closes: #552190)
  * test_deb822.py: Update to support new gpg "SIG_ID" algorithm
  * 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)
  * Use the apt_pkg.TagFile iterator interface instead of hacking its
    offset.  As of python-apt version 0.7.94, that interface doesn't use
    shared storage. (Closes: #571470)
  * debian_support: Add a native python Version class, based on Raphael
    Hertzog's DpkgVersion class in the PTS (Closes: #562257, #573009)

  [ Jelmer Vernooij ]
  * Remove unused imports in the debfile and debtags modules

  [ John Wright ]
  * changelog: Use debian_support.Version directly
  * Deprecate the 'debian_bundle' package in favor of a new 'debian'
    package (Closes: #570210)
  * debian_support: split tests into tests/test_debian_support.py for
    consistency
  * Convert to "3.0 (native)" source format and update Standards-Version
    to 3.8.4 (no changes necessary)
