I'd get a second opinion on that. That looks like the metal of the dropout is exposed close to the joint where the seatstay is bonded. Carbon + aluminium means that it would have to be bonded together. Like I said before, this may be more than a cosmetic problem.
I'd also ask about the warranty. Some manufacturers have a transferrable warranty, some don't. I'd also be interested in what Felt would have to say about that sort of damage.
