Subject: endgame position - null move problem

Here's a position that occurred in a recent offline test game:

{D] 8/6r1/p7/1p6/3kBn1P/P2p1P2/1P6/3R1K2 b - -

Ke3 is winning here, but Arasan 6.3 doesn't get this, in fact it wants to play
Rg8. It is apparently a null move issue. If I turn off null moves, or restrict
the null move in the case where the opponent has an advanced passer, then it is
solved quickly.
