Harvest from/Save in CCK Filefield : Fatal Error

Hi

I'm a newbie in Media_mover sphere, but thanks for the good work, this module seems amazing

However, I have a (kinda major) bug when trying to save a node :

Fatal error: Cannot use object of type stdClass as array in /sites/all/modules/filefield/filefield.module on line 163

FYI :
I am using
Drupal 5.16
MM 1.0-rc7
Filefield 2.4

Here is my MM config :

$configuration = new stdClass;
$configuration->required = array('mm_cck', 'mm_ffmpeg', 'mm_cck', 'media_mover_api');
$configuration->name = 'All videos to FLV';
$configuration->cid = '4';
