Using ZendFramework 1.10.0alpha1

A change in r18965 to Zend_Form_Element->getLabel() has added translation of the label at this stage.

However, Zend_Form_Element_Submit->getLabel() translates this value again:

    /**
     * Return label
     *
     * If no label is present, returns the currently set name.
     *
     * If a translator is present, returns the translated label.
     *
     * @return string
     */
    public function getLabel()
    {
        $value = parent::getLabel();

        if (null === $value) {
            $value = $this->getName();
        }

        if (null !== ($translator = $this->getTranslator())) {
            return $translator->translate($value);
        }

        return $value;
    }

This could lead to some very subtle mistranslation artefacts.

A possible fix would be to only translate if the label in Submit is retrieved from getName() as below:

    /**
     * Return label
     *
     * If no label is present, returns the currently set name.
     *
     * If a translator is present, returns the translated label.
     *
     * @return string
     */
    public function getLabel()
    {
        $value = parent::getLabel();

        if (null === $value) {
            $value = $this->getName();
            if (null !== ($translator = $this->getTranslator())) {
                return $translator->translate($value);
            }
        }

        return $value;
    }
