[pbmserv] Bug (?) in Zertz game

[Urban Hafner <urbanhafner@gmx.de>]

Hej,
there seems to be a bug in the zertz engine. The problem is
with game 1245. After my last move I recieved a mail with this
position:

     A4 B5 C6 D7 E6 F5 G4     ** Zèrtz (tournament) **
              __
             /  \
        __ . \__/.  __        [marbles]    white   gray   black
     __/  \__/  \__/  \__
    /  \__/  \__/  \__/  \    reserve:       3       5      4
    \__/  \__/B \__/  \__/
    /  \__/  \__/  \__/.      player1:       3       0      1
    \__/  \__/  \__/  \       player2:       0       2      4
    /  \__/  \__/G \__/.
    \__/  \__/  \__/.  __
     . \__/  \__/.    /  \
        . \__/  \   . \__/    next player: [player2]
           . \__/.            next action: add a marble, remove a tile
              .


     A1 B1 C1 D1 E1 F1 G1

If I rightly remember the zertz rules the tile at G1
should be removed.
