If the translation module is enabled, the init() method of the class commerce_customer_handler_field_customer_profile tries to access the language column of the table commerce_customer_profile.
Since the data of the customer profile are language independent anyway, the usage of a language column is superfluous - especially since this column doesn't even exist ;).
