For reasons unknown, it does not happen on Mathematica 5.0:

renan@nightfall :~$ math
Mathematica 5.0 for Linux
Copyright 1988-2003 Wolfram Research, Inc.
 -- Motif graphics initialized --

In[1]:= D[{x[1],x[2],x[3]},{{y[1],y[2],y[3]}},NonConstants->{x[1],x[2],x[3]}]

D::dvar: Multiple derivative specifier {{y[1], y[2], y[3]}}
     does not have the form {variable, n} where n is a nonnegative machine
     integer.

D::dvar: Multiple derivative specifier {{y[1], y[2], y[3]}}
     does not have the form {variable, n} where n is a nonnegative machine
     integer.

D::dvar: Multiple derivative specifier {{y[1], y[2], y[3]}}
     does not have the form {variable, n} where n is a nonnegative machine
     integer.

General::stop: Further output of D::dvar
     will be suppressed during this calculation.

Out[1]= {D[x[1], {{y[1], y[2], y[3]}}, NonConstants -> {x[1], x[2], x[3]}],

>    D[x[2], {{y[1], y[2], y[3]}}, NonConstants -> {x[1], x[2], x[3]}],

>    D[x[3], {{y[1], y[2], y[3]}}, NonConstants -> {x[1], x[2], x[3]}]}
