[ODE] Trimesh-sphere collision detection debugging

I would start by printing the body ID and the position of the geoms that 
are colliding. Perhaps the geom isn't actually connected to the body, or 
perhaps the bodys position is not where you think it is.

Collision is very deterministic, so because you have a reproducible 
case, it should be a simple matter of standard debugging techniques to 
figure out why it's happening.
