Shouldn't be emitting a message inside of try/catch

[selfcontained]

We wrap a JSON.parse() inside of a try/catch - but also emit a user-facing event there inside of the try/catch. This can make debugging errors difficult, as it looks as though it's coming from a JSON.parse issue. We should probably move the event emitting to outside of the try/catch block, if we parsed the message successfully.
