[Lucid] apt-get source always selects highest available version instead of the specified one

This is marked as fixed in 0.7.25.1, but still happens with 0.7.25.3ubuntu1 for me:

$ amad amarok | grep Sources | egrep 'lucid|karmic'

Bumping Importance: makes "apt-get source" useless for anything than the most recent version.
Also, the "--only-source" workaround mentioned in the Debian bug does not work for me.

Actually I can confrim again that apt behaves odd again:

$ apt-cache policy mediatomb
mediatomb:

     0.11.0-3 0

apt-get source mediatomb/stabe -> downlaods stable
apt-get source mediatomb/karmic -> downloads karmic
apt-get source mediatomb/unstable -> downloads lucid
apt-get source mediatomb/testing -> downloads lucid
apt-get source mediatomb/lucid -> downlaods lucid

And getting by version fails for me too

Hello,

a couple of points:
$ apt-get source amarok=2.2.0-0ubuntu2
does not work correctly /gets the lucid source) and does not show a message. this is a bug (and a regression to karmic).

But
$ apt-get source amarok=2:2.2.0-0ubuntu2
does work correctly and gives the right version.

As for:
$ apt-get source amarok/karmic
gets the lucid source.

Could you please check that:
$ apt-get source amarok/karmic
works if you have both "deb" and "deb-src" urls. But not with only deb-src URLs (this is a old bug).

Some further looking shows that:

# ./apt-get source -d amarok=2.xxx

It prints a warning at the end - I make this a hard error instead now.

This bug was fixed in the package apt - 0.7.25.3ubuntu2

    - add set_apt_proxy_from_gconf() and run that once on upgrade if
      there is no proxy configured already system-wide (LP: #432631)
      From that point on gnome-control-center will have to warn if
      the user makes changes to the proxy settings and does not apply
      them system wide

  * Change the package index Info methods to allow apt-cache policy to be
    useful when using several different archives on the same host.

This isn't entirely fixed IMHO, or a regression has occurred - the only way I can get an old version's source is if I have a corresponding 'deb' line in my sources as well as a 'deb-src' line, which is inconvenient. I think that solely the 'deb-src' line should be required for getting sources.
