JSONP handler in 1.4.3-RC3 seems broken

[gfodor@…]

I'm testing an existing jQuery app and when using JSONP I am getting a "no such node" error. The culprit seems to be inside of the ajax function:

} else {

Garbage collect window[ jsonp ] = undefined;

try {

delete window[ jsonp ];

} catch( jsonpError ) {}

}

if ( head ) {

head.removeChild( script );

}

In this case, when the JSONP callback is called, "script" seems to be unbound. ("script" is declared later in the file.) I'm not sure of an appropriate fix, but his certainly seems broken.
