Noting that I can't reproduce this; it might have been the result of attempting to edit an order prior to 'hitting' the admin's Modules->Shipping first (so that the no-longer present shipping module is removed from the configuration).
If the shipping module used when the order was placed no longer exists on the site, a fatal error will result when the order is edited. This can happen, for instance, if a shipping module is removed during an upgrade and a pre-upgrade order is edited.
