Exported nodequeue missing subqueue

I have a Feature with an exported Nodequeue, using the Simple Queue type. The Nodequeue gets exported with 'new' => FALSE,.

I'm not sure if this happens in other conditions, but when I enable the Feature as part of an installation profile, the Nodequeue gets created, but not the subqueue, so I end up not being able to add items to the Subqueue and there is not an easy way to create the subqueues automatically from my installation profile.
