Titanium Appcelerator Final Package Build Crash (Log Included)

I'm running into a problem with my final iPhone app build before I send it off to the App Store for approval. This is the first app I've built.

The app sometimes crashes on the actual device I'm testing with (an iPod Touch 2nd G, which is all I have at my disposal), but never in the iPhone simulator. Titanium Developer doesn't spit out any other errors either.

Here's the build/iphone/build/build.log file:

Does this have something to do with acquiring the proper distribution keys?

The only time I get that error is when the provisioning profile is missing or not hooked up properly to a certificate in my keychain. Have you tried this in TiStudio instead of TiDeveloper?
