"null" is null or not an object error in IE

Question

Now I get this strange error from IE, which is basically

'null' is null or not an object

The line number that he gives is completely disabled, so I do not attach much importance to it, but, apparently, I narrowed it down to the place where it came from.

function openSong(songlink){
     $('#smallbox').slideDown();
     requestCompleteSong('<tr><td>'+songlink+'</td></tr>');
  }

There are no errors from IE in the above code, however, when I make an AJAX GET request using jQuery, it seems to throw this error

function openSong(songlink){
     $('#smallbox').slideDown();
     $.get("getSong.php?fake="+makeid(),{ id: songlink },requestCompleteSong);
  }

'songlink' is definitely not null because the first function I posted works fine. Here is makeid ().

function makeid()
{
  var text = "";
  var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

  for( var i=0; i < 5; i++ )
    text += possible.charAt(Math.floor(Math.random() * possible.length));

  return text;
}

Can anyone understand why IE is throwing this error?
