I've sent the bug report. But for in the mean time, I've found a workaround.
If I delete (or rename) the movie, space.bik; then the game no longer crashes. Of course, I don't get to see the movie, but at least I can win the game without it crashing! Also, if I switch the intro.bik file with the space.bik file then I get to watch the space victory movie when the game starts up.
This is just a crappy workaround, but at least I can win without it crashing, and I get to see the victory clip.
