Comment 5 for bug 703472

Fixed in python-apt's debian-sid branch. This should land in natty once we fixed some
other bugs, merged it and tested it. Please do note that architecture is a property
of packages in APT, so installed still returns one version, but there are multiple packages
now, such as apt (or apt:amd64) and apt:i386 on and amd64 + i386 system.
