Magento sql Problem with Submit Shipment button in admin

In admin, we cannot submit order shipment; in "Items to Ship" does not appear any product and also isn't possible to ship nothing, no "Submit shipment" button, etc. By inspecting page we have found this error; //<![CDATA[ [login to view URL]("dom:loaded",function(){packaging=new Packaging({"createLabelUrl":"http:\/\/[login to view URL]\/[login to view URL]\/tessin_adm_str\/sales_order_shipment\/save\/order_id\/1889\/key\/d9ec1c3ce21d3e3f76e0784a35aacee1\/","itemsGridUrl":"http:\/\/[login to view URL]\/[login to view URL]\/tessin_adm_str\/sales_order_shipment\/getShippingItemsGrid\/order_id\/1889\/key\/1e661cbef52ad72576fdf18e46072bb9\/","errorQtyOverLimit":"The quantity you want to add exceeds the total shipped quantity for some of selected Product(s)","titleDisabledSaveBtn":"Products should be added to package(s)","validationErrorMsg":"The value that you entered is not valid.","shipmentItemsQty":{"5254":1,"5255":1},"shipmentItemsPrice":{"5254":"1.6400","5255":"1.2300"},"shipmentItemsName":{"5254":"Campione Tessuto Ecopelle Floccata Broccata Ecr\u00f9 Panna","5255":"Campione Tessuto Ecopelle Nero Glitter Oro"},"shipmentItemsWeight":{"5254":"1.0000","5255":"1.0000"},"shipmentItemsProductId":{"5254":"2669","5255":"708"},"shipmentItemsOrderItemId":{"5254":"5254","5255":"5255"},"customizable":[]});[login to view URL]($$('select[name=package_container]')[0]);[login to view URL]($$('select[name=package_container]')[0],0);}); //]]>
