New Post: Ciritical error when adding product to checkout or going to the checkout page

UPDATE:

we have done a an xml product export of all products and imported them into a test store and the test store is thwowing the same error on the same products.

My conclusion is that the xml must contain the issue but I just can't see it...
you can download the xml and have a look if you like
