Comment 3 for bug 1252079

i did had the same error, simple solution to get around is to add the field type to product_product.

so in models/product.py - at class product_product

    _columns = {
        'prestashop_bind_ids': fields.one2many(
            'prestashop.product.product',
            'openerp_id',
            string='PrestaShop Bindings'
        ),
        'type': fields.char('Product type', size=128),
    }

this will fix the bug
