Hmm I first thought all include-links packages would cause similar warnings for some files, but it's not the case; the problem appeared on my system after 4.0-0ubuntu2 and does not appear on new installs (the timestamp of the file is the date of installation of 4.0-0ubuntu2 which is the last version using python-support). In 4.0-0ubuntu3, it was converted to python-central + include-links; I guess this needs a manual cleanup call to python-support's update-python-modules.
