Cannot add non-free to debian live buils

[* SAMÍ * <miaousami@hotmail.com>]

Hi guys,

I am trying to generate my own live debian using stable live debian tools.
I want to add some non-free packages, so I try to use --archive-areas 
"main non-free"

It seems to have no effect, and during build time, only main is used so 
my non-free packages are not found.
Below is my config script.
Any suggestion ?

By the way: I really love these live scripts :-)

lb config noauto \
--distribution squeeze \
--archive-areas "main non-free" \
--architecture amd64 \
--binary-images iso-hybrid \
--bootappend-live "boot=live noeject config keyboard-layouts=fr" \
--debian-installer false \
--debian-installer-gui false \
--memtest memtest86+ \
        "${@}"

Regards
Sam
