adding fee amount does not work together with enabled entity_translation

Playing with the latest versions of commerce 7.x-1.11 commerce_custom_product 7.x-1.0-beta2(+dev) and entity_translation 7.x-1.12 i recognised that enabling the translation for an referenced Term on a custom line item (as josh explained with the pizza shop) disables the right calculation prise. Not enabling the entity_translation module disables die calculation done by rules, only enabling the translation for the referends field (term with prise). Allready posted https://www.drupal.org/node/2455653, unclear which module produces the bug.

Has sombody run into it before? Any ideas what to do?
