[ODE] TriMesh/Box Problem

I need to correct myself here after some more tests.
Maybe this information could help someone find a bug in the
box/trimesh collision code.
I have a ground made with 1 huge box geom when i drop a trimesh on it
everything works fine if the box (ground) is smaller than the trimesh.
In my test i drop a torus 6x6 on a box 5.9x5.9 and it works as
expected but if i drop it on a box 6x6 or more it goes to space.

So from my observations trimesh vs box works as long as the trimesh is
larger than the box.

There is no problem with spheres of all sizes.
