I'm guessing that somehow a chunk of their source code got marked as "copy to the bundle" from within the project's build phase. One scenario I could think of this happening is a bug in a custom build script that was intended to copy other resources (images, sounds, etc.) to the bundle and copied an unintended directory containing the leaked source code as well.
