somethine wrong in nodefamily/CONTENT_TYPE

Hi,
I'm just testing the port of node profile for d50. I've created a new content type (profile).
It is correctly associated with usernode. Now if I try to access the edit page for the first time
with /nodefamily/profile, the edit page is correctly prompted. If I try to access it a second time,
the update page simply shows (Array).

The content type I'm using has only a single field (Name) and no body. The problem should be
in nodefamily_lonely_node_page in the return node_form($node); function.

I don't understand what's wrong...
