My initial thought was that the door was made of unsuitable materials, particularly the fingers, or that an operation left a gouge to raise stresses; that thought has been put aside.
The rigidity of tubular fuselages limits torsion deformation. Without deformation there isn't much stress on the door. The main stress is from the pressure load which puts bending loads on the fingers, but if they had failed the guide rollers would likely have been torn loose and they are still present.
