Female gender does not work

[Athris]

If you choose in the custom profil fields for example
Race: Human
Class: Warrior
Level: 50
Gender: Male
--> It works. I get the human warrior male avatar.

Change the gender to female
--> The avatar does not change.

I look into the pbwow.php and if i change
$wow_g = max(0, $wow_g - 1); in line 820
to
$wow_g = max(0, $wow_g);
it works, because now the avatar path is 1-1-5. Without the change it is 0-1-5 by female. Do you can reproduce the problem?
