Crash maybe related to the refinery status

[TripH]

Okay, I did my best to really narrow this down, here you go:
When the refinery has about 60+ units on it's counter, the game crashes when I press Alt, go into another screen (up, down, left or right) and then go back to the middle screen. About a few frames before the scrolling-in middle screen hits it's final position, the game crashes (Blackbox below).
Strangely enough, I have no units selected (it's not the officer issue) and the refinery status has to be somewhat over 50 for this to happen. I've tried maybe half a dozen times (man, that sucked having to play to this point over and over again), and it's absolutely reproduceable. As soon as I am at 50+ units and go to another Alt-screen and back, it crashes.

Edit:
I forgot to say: It's clearly not about the sheer time played, I've just let it run for a night and nothing happened. Well, except this "viruses-turning-into-a-large-ball" issue, but no crash.
