It looks like one of your plug-ins is causing you to crash. My guess is that you're visiting a certain page which uses flash (your only internet plug-in loaded).

So I would suggest making sure you are up to date with the latest version of Flash. Then keep an eye on pages you load regularly, it's possible that not all flash content will cause the crash. If it's a particular page though (you may not even have it open at the time of quit) that seems to initiate the problem, we'd love to take a look at it. (We probably wont be able to do anything if it's truly a plug-in crash but we can at least take a look).

P.S. I edited down the crash in your note to make it a little smaller and easier to read relevant parts.
