This crash happened post endgame with the Shakturi storyline after I defeated them by taking their homeworld, as I like to play sandbox style. I uploaded a savegame called "Dejavuproned-Jan22-11-v1.05.01-GxBOCrash.dwg". It happens a little bit after and there doesn't seem to be any big event that triggers the crash, and I reloaded a half dozen times and though things always played out a little differently each time it always crashes after approx the same amount of game time elapsed.
This sucks, because I hate starting new games just because a crash rendered my previous one useless
