js dump not possible if i18n for route is enabled

It is not possible to dump the translation is the i18n for routes is enabled.
I try the command: php app/console bazinga:expose-translation:dump
and i got the error: 
Fatal error: Call to a member function getRequirements() on a non-object in /Users/thomas/Workspace/guestapp/vendor/willdurand/expose-translation-bundle/Bazinga/ExposeTranslationBundle/Dumper/TranslationDumper.php on line 92
This route is technical and should not be i18n.
