some users reported that they had no CTD with the original game. After updating to the EE they get the same problem as other ppl...
One more thing i found out to "trigger" the CTDs.
as the game just add saves to the save list and didn't overwrite older ones u can have a large amount of them. when i start to delete some (read as > many) in a row, the game crash in the same way while playing it...
even from the main menu it happens. i can't say it has to be an exact amount of deleted files... it just happens while doing it...
If it crash this way, it also freeze my steam.
