Subject: Null moves in pawn endings?

Is null move technique always incorrect in pawn endings with zugzwangs?

I try to implement null moves in my program; and it fails to solve simple
ending:

White Ke4, Pd4; Black Kd7 -> 1. Kd5 +-

Without nullmoves my program sees winning on ply 13; with nullmoves it fails to
solve this position.

Even when I allow two (and no more) consequtive nullmoves it does not help.
I thought that double nullmove should work here, but it seems not...
Why?
