Bug#565364: python-apt: Auto flag attribute in apt_get.Package is always 0

[Gene Cash <gene.cash@gmail.com>]

Package: python-apt
Version: 0.7.13.3
Severity: normal

Run this code:

import apt_pkg

apt_pkg.InitConfig()
apt_pkg.InitSystem()
cache=apt_pkg.GetCache()

for pkg in cache.Packages:
    if pkg.CurrentVer and pkg.Auto != 0:
        print pkg.Name

This prints only:
Reading package lists... Done
Building dependency tree       
Reading state information... Done

You'd expect it to print at least one package on a normal system.

For example, look at a short excerpt from my /var/lib/apt/extended_states:

Package: python2.4
Auto-Installed: 1

Package: gcc-4.3
Auto-Installed: 1

Package: cpp
Auto-Installed: 1

Package: libgmp3c2
Auto-Installed: 1

Package: gcc
Auto-Installed: 0

So at least python2.4, gcc-4.3, cpp, and libgmp3c2 should be listed.
