i have same the problem. It crashes with different Tracks when i'm loding them into my decks, especially when i load tracks from the iTunes Collection. The only possibility to open Recordbox again after it crashed is a full restart of my Macbook! Otherwise the Recordbox logo will popup and disappear a few seconds later with the result that Recordbox isn't open.
I have this problem also with a clean and fresh install of Snow Leopard and Recordbox.
