I don't know what it means, but the crashed thread is making the same call: 511 com.adobe.InDesign.Print 0x17bf6703 GetPlugIn + 497427 more than 500 times. Are you exporting to PDF, or printing?
I think I figured it out. I'm pretty sure one of the linkes photos was currupt or casing something weird to happen. Once I replaced those I was able to make export a PDF as a file just fine.
