[Freeciv-Dev] (PR#2755) AI hangs at modified rulesets

["coppensbart@xxxxx via RT" <rt@xxxxxxxxxxxxxx>]

(CVS of 03/01/2003; no additional patches applied)
While trying to edit some values of my rulesets and playtesting certain 
positions of units, I came across this. I have A 3-player savegame. All three 
are set to human. For testing, I tried to play as Aragorn against Sauron. So 
I set Sauron to AI. When I started the game; civserver didn't respond 
anymore. Backtrace of the killed (Ctrl+C) civserver:
> start
Starting game.
>
Player 'Sauron' now has AI skill level 'easy'.

Program received signal SIGINT, Interrupt.

Reproducable: always. Just load the savegame below with the rulesets, set 
Sauron (Aragorn has the same result) to AI and start.
