Firefox Crashes on Gmail

Last week I noticed that every time I tried to compose an email in Gmail, Firefox would have a hard crash. I figured it was something in the javascript and left Gmail alone for a few days since it is Beta. This week I decided to try it again and I experienced the same behavior. In an effort to debug this problem I tried Gmail in all the browsers that I had installed. I had the same crash in Camino and Opera but it worked fine in Safari. After much poking around I found that my Palatino font was corrupted. After replacing the font everything was fine.
