I caught this during 1G too but it didn't attract any forum attention.  Basically, holding down the space bar can break the game.  The turn changes rapidly even while a dialog prompt is up.  The prompts stack up and can be addressed one by one if you let go of the space bar before the game crashes.

I skimmed the debug file myself and it appears that bandits and ogres attack somebody at some point.  It's my suspicion that the game crashed when my Sov was killed but I have no idea because the first prompt that popped up blocked my sov...
