Les détails d'activité dans la liste des sujets échouent lorsque la locale par défaut est bosanski jezik

Since we updated our Discourse to v2.3.0beta10 on list of topics details shows error en_US.dates.tiny.x_minutes.other

Our discourse is set to bosanski jezik in default locale.
Is this missing translate or bug.
When I set default locale to Englis, there is no errors.

This looks like the same (or very similar) problem that is described here.
