UFO:AI consistently crashes now.  This started occurring a couple of months
ago, but I don't know which is the last working version.

Steps to reproduce:
- Start UFO:AI
- Select "Single-Player"
- Select "Skirmish"
- Choose a map and "Start Game", I tested with the africa_small and a few
others.

The game loads, and the screen announcing the map and "Victory Conditions"
shows up.  You can move the map in the background and it renders fine with no
errors or crashes with multiple graphics configurations.  One the Start button
is pressed it crashes after a couple of seconds.

This is output from the console==========

Don't know how to debug this, but I'd like to help, and finish my game in
progress. :-)
