Hmm, interesting and the first I've heard of this. I wouldn't imagine you could hit anything hard enough with just the tire to crack a rim unless the rim already had a defect. While it is true the different type of sidewall and composite used in the RFT is 'harder' it would not crack a rim by passing on force. If it could you would see far more posts about this.

Depending on the age, I would almost consider saying that the wheel had a defect. Look around the site of the crack, look for curb rash or scuffing of the rim that would indicate you hit something with it. Also, if they pull the tire off the rime. Take a look at the inside of the rim, look for hairline cracks inside that the tire may have been hiding. I just don't buy the dealers excuse if you did in fact NOT hit something with the wheel.
