Our Python 2 package has a bunch of patches (numbered 100 and above) that allow to disable the build of a number of extensions that are not necessarily useful in all situations. Those patches should be upgraded and added in our Python 3 package. At the moment, the Python 3 installation takes 55 MB in /usr/lib/python3.3/, which is way too much.
Maxime, ping? :-)
Fixed by Maxime in git (f1c092da8ba4d), thanks
It has already been fixed since a while, update the bug status to reflect this.
