Ok, the bug is fixed. It just comes from the fact that we usually solve 
        -(dx(dx(V))+dy(dy(V))+dz(dz(V)))=0;
and not   dx(dx(V))+dy(dy(V))+dz(dz(V))=0;
so I did forget to test it and implement it...

Note also that the scene is useless here since you are using standard FEM and 
not fictitious domain.

Best regards and thanks for the report,
Stephane.
