Mountain Lion GM is installed, upgrade install (yeah, I know). I've cleaned every possible cache, etc. The problem happens on the guest account too. Here is the crash log. I can open Safari and look at preference menus, etc but going to any site makes the site start to open then it immediately crashes. I shortened the crash log a bit.
