Details:

The following used to work in 3.6.4 and works in Matlab:


su = surface ();
set (su, "vertexnormals", get (0, "factorysurfacevertexnormals"))
## error: invalid value for array property "vertexnormals"
-verbatim+

Here the factory default is an empty matrix (as in matlab), but there is a
constraint on "vertexnormals" that prevent empty matrices. It was probably
introduced by changeset [1]. 
I attached a patch.
