Therm, what do you mean by "gore"?
You're probably right about some measure of mis-alignment or a jamming of the chain. I went through the links of the chain once I got it off, and they all seemed fine. I think the chain jumped the teeth on the chainwheel and got caught and pulled the un-supported section down. The fact that it is a 3-arm crank probably weighs-in, as-well. I do not own a camera, and have little intent to purchase one. If you have any questions, ask.
