When compiz crashed I lost my keyboard so I couldn't enter a bug description. I copy pasted some random text using the mouse.

What I did to make compiz crash is I pressed Win + E. The same key combination worked in a previous graphical session so I don't know what exactly went wrong this time. I am running the development branch (Natty) using a daily-live ISO from Dec 29th 2010.
