Yes the crash works every time with the game I was playing. I started the game in v24, converted to v25 and when I got to this point in v25, the crashes started. Went back a few turns, crashed again at this turn. When I heard about the svn version I thought I'd give that a try; I used the version from yesterday. Still the crashes during the AI turn. As we speak I am downloading r3442...
If it still crashes please post the savegame in which pressing end-turn crashes it.
