After playing for 80 turns, I decided to abandon the game and start a new one. I hit escape, brought up the main menu, and selected "New Game". The game crashed.
Dump file (with debug.err included in the zip) is here.
I know that this problem was reported during the beta, and it was stated that it was low priority to fix during the beta, but I thought that it was implied that it would be fixed before release.
