By far the biggest AI flub that I've seen was when barbs killed my settler (and civ) off in a turn after 4000 bc. with partisans, who spawned out of a goody hut.
I've also seen settler starts in places where no human life could possibly exist, such as a gigantic glacier continent, leading my civ to starve to death without a chance.
