I think that the trimesh only works correctly with spheres in ode-0.39. Try 
the CVS version from ODE

Some relevant comments from CVS:
opende/ode/ode/src/collision_trimesh_box.cpp 1.3
	- New trimesh box collision function from scratch.
opende/ode/ode/src/collision_trimesh_box.cpp 1.4
	Small bug in the triangle-box function.

So it probably works better now.
