see the thread transformBox broken in Bug Reports forum. might help.

I can't really believe nobody noticed this before... matrix4::transformBox consists of the following code: //! Transforms a axis aligned bounding box inline void matrix4::transformBox( core::aabbox3d<f32> &box) const { transformVect(box.MinEdge); transformVect(box.MaxEdge); box.repair(); } This ...
