I haven't seen it but anything can happen. Being that the belt has a problem every 4th tooth I would look at the front pulley being the problem not the rear pulley.
If you still have a warranty on the bike roll the dice and take the bike to the HD dealer for repairs. If the front pulley is broke it should be covered under warranty and the damaged belt should be cover too.
If there was another issue that caused the belt damage such as a rock stuck in the pulley then you will have to cough up the money for the repairs.
