Safari is crashing on my MacBook Pro on a fairly regular basis. It's completely trouble free on my iMac, and yet both machines have the same plug-ins, extensions, etc. installed.

Here's some of the crash report:

Anyone have an idea?

Have you got any add-ons installed for Safari? They are in the system library in /Library/Input Managers or in the user Library in ~/Library/Input Managers.

I have SafariCookies (SIMBL) on both machines, but the MacBook is the only one crashing so I'm not sure it's related to that.
