SRU: python-imaging missing dependencies (edgy)

[.:. brainsik]

During the new python policy transition python-imaging lost its ${shlibs:Depends}. This causes dependencies like
libc6, libfreetype6, libjpeg62, and zlib1g (which are critical to the function of python-imaging) to be missing. On desktop machines these dependencies are brought in by other packages but on a server install they aren't.

This bug was fixed with 1.1.5-11 in Debian and Feisty.

I have just added the ${shlibs:Depends} back in as version 1.1.5-11 does. See the attached debdiff for full details of changes.

Fixed in Feisty:

python-imaging (1.1.5-11) unstable; urgency=low

  * python-imaging-sane: Depend on python-numarray. Closes: #382190.
  * Add dependencies on ${shlibs:Depends}, lost in -6. Closes: #378596.

Here's an example of how removing libjpeg62 breaks python-imaging. The main problem is libjpeg62 was a dependency in dapper, but is not in edgy, so upgrading via aptitude causes libjpeg62 to be removed as "unused". This broke the web app running on the server being upgraded.

debdiff for edgy-proposed backporting fixes from 1.1.5-11

[Colin Watson (cjwatson)]

http://librarian.launchpad.net/5428992/python-imaging_1.1.5-10ubuntu1%7Eprop1.debdiff approved for edgy-proposed.

[Martin Pitt (pitti)]

Sponsored upload and accepted into edgy-proposed. Please go ahead with QA testing.

[Michael Vogt (mvo)]

I verified that the dependencies are now ok with the version from edgy-proposed, the package installs fine and pulls in the required dependencies (as expected).
