@Matt: IIRC you are hittnig this because you have a parse error in one of your JSNI methods. Either apply my patch and try it again, or else binary search for the offending method by commenting hafl of them out at a time. The good news is the error will likely repro in hosted mode, so it shouldn't take too long.
