Vault crashing

[Gabo-Lin Gabbering Goblinto]

I'm running on a early 2008 macbook. Since the beginning of the game whenever I hit a vault after I try to exit it crashes my game. I thought it was simple enough to just avoid the vaults, but in Waterloo, which was my favorite level when I played when I was younger, has a vault that I am required to hit in order to progress. http://i.imgur.com/oXGmTaL.png Here's a screenshot of the crash report if that'll help. Thank you.
