Its Weird, This looks to me related with Taxes setup.

Can you check that your taxes have some value in Name/Display name? if not assign some value and try again.

or in sql run ecf_GetTaxes by assigning same values as you are passing to this function and see what taxes it is returning.

Hi K,

The problem is not occurding everywhere, It's only on some browsers.

Your anwer helped us to investigate in right direction.

ecf_GetTaxes has a parameter language culture and this value is an input from Browser culture. So if order was made from somebody sitting in UK and then somebody from US will try to view the order, it will throw the exception, because en-US culture is passed to this SP.

Thanks for your help

Shaan

I guess one of these properties of the Shipping address might be null instead of empty: CountryCode, State, PostalCode, RegionCode, City. But we need to find out why it is null. Do you have any modification to the Workflow/Activities package?
