after the first game, freecell segfaults when you choose "yes" to the question "play again" or when you say "no" and then click "new game".
Do you mean AisleRiot or Freecell? I am unable to duplicate this.
/usr/bin/freecell just try to play another game after winning one.
This is fixed in GNOME CVS. It will be in the next release of gnome-games
