I have actually crashed because of that before. T2 at Barber Motorsports Park on my 675 about 5 years ago, drug the peg hard enough to unload the back wheel...which overloaded the front wheel and boom...ate .....
But with the Gilles, it was actually when I was standing on the outside peg while pouring on the gas exiting one corner, prior to preparing to enter another one. The damn peg just broke/sheared off. It is a weird feeling when you are weighting the outside peg and suddenly your foot goes to the ground.
