Fix handling of nicks that start with { or [

  Didn't know this:

  When the data attribute is an object (starts with '{') or array
  (starts with '[') then jQuery.parseJSON is used to parse the string;
  it must follow valid JSON syntax including quoted property names. If
  the value isn't parseable as a JavaScript value, it is left as a
  string.
