Crash when receiving invalid JSON response

[inghamn]

For various reasons, an Open311 server may spit out invalid JSON in the response. Right now the app just crashes when this happens. We need to do error checking on the response and handle it in a nicer way.

The Cocoa errors 3840 is coming from uReport spitting out an HTML error message in the JSON response. I'll need to also make sure uReport only spits out JSON errors.

If I POST to it using Open311 Generic POST (Content-Type: application/x-www-form-urlencoded; charset=utf-8\r\n
\r\n
api_key=XXXX=&jurisdiction_id=matthewncockburn.com&first_name=Matthew&last_name=Cockburn&&service_code=1&lat=55.5&long=-2.55&\r\n
attribute[WHISPAWN]=123456&attribute[WHISDORN]=COISL001) I get:
