problem with $.getJSON( )

problem with $.getJSON( )

Hi all,
 
I am having an issue with json returned from my server. I keep getting the following error when jquery executes this function:
<code>
// process the data (runs the xml through httpData regardless of callback)
data = jQuery.httpData( xhr, s.dataType, s );
</code>

Error: $lineinfo is undefined

Here is the json i am returning from the server. any help is much appreciated.
