Copy/Translate on Free Object in 4.1 breaks JForm Associations

[Giuse69]

After upgrade from 4.0.6 to 4.1, when I try to edit in backend any object of a custom type that uses the JFormAssociation field, I get a critical error "Cannot use object of type stdClass as array". Stack trace: #0 [ROOT]/libraries/cck/_/cck.php(34): plgCCK_Storage_LocationJoomla_Article_Helper::getAssociationsForm()

Troubleshooting the problem, it appears as the new feature Copy/Translate feature commited with https://github.com/Octopoos/SEBLOD/commit/90bbc1eba5a3cc4bf63586cefc5b9ea42fc05248 has broken the usage of the AssociationField at least with Seblod custom types. Infact reverting line 84/85 $form = ....array( $id, $name, $field, $config ) to the previous version $form = .... array( $id, $name, $config ) everything works again.
