I just had a crash occur shortly after loading a saved game. (NOT savescummed) The odd thing about it was that even though it gave the message saying to copy down the error information, it didn't show any lines of error information until I finally X'd out, at which point the lines flashed for a fraction of a second. Unfortunately, I was barely too slow hitting the print screen button to capture those lines, and because I tried my SS of the crash itself was overwritten with a SS of my desktop. >_> (I had hit F9 and F10 as well, but they appear not to work during a crashed game.)
So no solid information, but it might be worth trying to reproduce.
