Strange apt-cdrom add behavior with a DVD iso image

["Guilherme P. de Freitas" <guilherme@gpfreitas.com>]

In short, apt-cdrom add writes the following line to my 
/etc/apt/sources.list:

deb cdrom:[Debian GNU/Linux 3.1 r0a _Sarge_ - Official i386 Binary-1 
 (20050607)] / unstable contrib main

As you can see, the "dists" component is labeled "unstable". I can't 
figure why.

I have downloaded the following ISO DVD IMAGE:

d6eeef5a49ff851839bc514cc56f305a  debian-31r0a-i386-binary-1.iso

using jigdo. I downloaded the .jigdo file

http://cdimage.debian.org/debian-cd/3.1_r0a/i386/jigdo-dvd/debian-31r0a-i386-binary-1.jigdo

and the corresponding template to get the ISO image. Has anybody 
else had a similar problem? Is it a jigdo problem?

Thanks everyone for the great work!

Guilherme

P.S. Please, cc me for I'm not in the debian-cd list.
