At a certain point, this controller is presented full-screen modal, does some setup, and invokes loadRequest: for its UIWebView. The URL always points to a local file.

You can get this "error" when the page automatically redirects via Javascript. I would recommend just ignoring the error, treating it as a non-error condition.
