Overture Crashes on path to refinary

[Zaiaku]

Hey, I have an issue at the momment. Every time I try to get to the Refinary, the game crashes and Linux asks me to sign back into my user profile. Happens every time without fail.

Using Ubuntu 10.4

Any ideas on how to remedy this problem.

And to be more spacific: On the way to the refinary, Just around the corner from the refinary door. Theres a path guarded by a dog there just before it. As soon as I pass the dog and go half way from there to the corner, it crashes.
