Do I have a bug?

Chess Tiger 14.0 and Gambit Tiger 2.0 both announce mate in 28 (that means they
think it is a mate in 29 starting from your position).

The line is:

00:32:36.2	 Mate in 28	20	354603928	Bb8 Kg2 Ne7 h3 Bh2 Kf3 Ng6 Kg4 Kf2 Kf5 Nf4
Ke4 Kg3 Kd4 Kxh3


I do not have all the tablebases installed, and it is why Tiger needed half an
hour on my K6-2 450 to find the mate (24Mb hash).
