I'm on the hard side of the Mountain!
That crank just plain old fatigued - can't credit my explosive power but maybe I gouged it somehow to get things started. It seems like the cross sectional shape of the thing just isn't very smart though. Anyway, do a good inspection on yours before you decide to swap it to a different bike.
Edit - there's been a recall on some Gossamer cranks too, maybe you can get a free replacement:
