[Addressed] Another odd crash...

[Hissy]

Allo' to you all! Just downloaded the new version. One small problem. Everytime I try to start a new game, it crashes. I've checked through the start up console, and found nothing. I got this error message.

If I overlooked something in FAQ or fixed bugs, please, no flames, sorry for being an idiot.
I am on my laptop right now, which has a video card with only 32 MB dedicated memory, so that could be a problem. Ill put it on my desktop and see what happens.
So, any help comrades?

Since I don't know what in particular went wrong here I just put the entire GL segs loader into an exception handler that forces a node rebuild if triggered.
