ITunes Crash When Attempting to access iTunes Store

Question

So, here's an interesting one for you. Every time I try to access the iTunes store, iTunes decides to crash on me. No error message, nothing. Just poof gone.
It worked yesterday when I plugged in my iPod Touch and got it running for the first time. Everything else I've tried on iTunes works (with the exception of .avi files not importing, but I assume that's normal). If I access the App Store via my iPod, it works. It's just the store interface in iTunes.

I'll go ahead and provide the entire diagnostic thing, since more information is always good, and the diagnostic's full text isn't that much longer.
