$.getJSON does not use "text json" converter

[rhoffman]

I was previously using jQuery 1.4.x, and upgraded to 1.5.2. Some of my calls to .getJSON have stopped working. If I change the calls to a regular .get, and then in the first line of the callback run jQuery.parseJSON on the result, it works fine. After some debugging, I have determined that the problem is with the new jQuery AJAX converter system and the .getJSON convinence method. If it is changed from:

getJSON: function( url, data, callback ) {
		return jQuery.get( url, data, callback, "json" );
	},

to:

getJSON: function( url, data, callback ) {
		return jQuery.get( url, data, callback, "text json" );
	},

the problem is corrected.

Unfortunately, I can not do this on jsfiddle, since this involves an HTTP GET request, and jsfiddle only supports POST requests.
