Bug#136791: apt: Preferences upside down?

[<jim@short.circuit.com>]

Package: apt
Version: 0.5.4
Severity: normal

I've recently noticed that apt-get no longer fetches from the local mirror,
unless the mirror is the only active site (system offline).

The mirror is listed first in sources.list:

# Local mirror
deb http://localhost/mirrors/debian woody main contrib non-free
deb http://localhost/mirrors/debian woody non-US/main non-US/contrib non-US/non-free

deb http://ftp.us.debian.org/debian potato main contrib non-free
deb http://archive.debian.org/debian-archive slink main contrib non-free

# Specials (mplayer, etc)
deb http://mplayer.nmeos.net testing/
deb http://marillat.free.fr/ testing main
deb http://mplayer.nmeos.net unstable/
deb-src http://marillat.free.fr/ unstable main

deb http://ftp.us.debian.org/debian woody main contrib non-free
deb http://non-us.debian.org/debian-non-US woody non-US/main non-US/contrib non-US/non-free

deb http://ftp.us.debian.org/debian unstable main contrib non-free
deb-src http://ftp.us.debian.org/debian unstable main contrib non-free


This is /etc/apt/preferences:
