comment Extending D for four-derivatives
I added the definitions PartialD[a_, S[var_, idx_List]] := 0 /; NumericQ[a] and PartialD[S[idx1_List, idx2_List], S[var_, derividx_]] := 0; to define the derivative for numbers as well as for the metric tensor. Works quite nicely now :)

comment Extending D for four-derivatives
Great suggestion! I just realized Mathematica will leave unknown expressions unevaluated, instead of setting them equal to zero.
