Ok, thanks to a previous message I found the solution:
http://groups.google.com/group/django-developers/browse_thread/thread/5c440115389b56a6/3139d2e61b81b908
I need to specify fields in my GenericRelation definition:
foo = generic.GenericRelation(Foo,
object_id_field='item_object_id',
content_type_field='item_content_type')
But I agree with webograph that it violate the DRY principle...
