[Plugin: Posts 2 Posts] Notice : post not defined through an array

Hi Scribu,

I’ve got a notice with WP-Debug :

Notice: Post type 'produit' is not defined. in /Applications/MAMP/htdocs/myproject/wp-content/plugins/posts-to-posts/core/type-factory.php on line 51

The relationship is defined through an array :

https://skitch.com/francoislamotte/8wyuf/post-type-is-not-defined

or the better with the code on pastebin

Every other custom posts are already defined in other relationships, so I guess there is a trouble with his array.

Do you need more information?

Here is the full P2P declaration in functions.php
