The dBodyID could be 0, and the mesh becomes a static environment.
see 7.2. dBodyID dJointGetBody (dJointID, int index); in the ode user guide :)

I am not sure of this will help, try directly call dGeomSetPositon when your
glove is moving. Since the static geom has no body, contact attach may
not work, but when the collision has been detected you can attach the
geom yourself. Something like 'glove.curHoldingGeom'.
