Hi there, I'm pretty sure I've found an interesting quirk/bug with the XSLT CommerceLibrary:EditShipmentInformation() Extension.

Steps to replicate: (replicated on a fresh uCommerce 2.0.5.0 install with demostore 1.2.0.0 running umbraco 4.7.0.378)
Set the displayName of one of your shipping methods to something really long.
In my case it was "UK Royal Mail First class Recorded Delivery (£4.95)"

(clear cookies before testing)
add an item to your basket and proceed to checkout,
Enter your address information, click proceed to shipping
you should receive an XSLT error: Error parsing XSLT file: \xslt\UpdateAddressInformation[XSLT].xslt

upon attaching to process from Visual studio to debug whats going on I got the following:

{"An error occurred during a call to extension function 'EditShipmentInformation'. See InnerException for a complete description of the error."}

Inner exception: {"String or binary data would be truncated.\r\nThe statement has been terminated."}

[NHibernate.Exceptions.GenericADOException] {"could not insert: [UCommerce.EntitiesV2.Shipment][SQL: INSERT INTO uCommerce_Shipment (ShipmentName, CreatedOn, CreatedBy, ShipmentPrice, DeliveryNote, TrackAndTrace, Tax, TaxRate, ShipmentTotal, ShipmentDiscount, ShipmentAddressId, ShippingMethodId, OrderId) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?); select SCOPE_IDENTITY()]"}

I know you probably shouldnt name your shipping method display names that long (that's what description is for right?) but it would be nice if this would be listed as a know issue or scheduled for a fix

thanks again
