it occurs：

when use $("[someAttr=someNumber]") like $("[someAttr=12345]");

when use .remove() to remove a div contains swfobject;

when a div contains swfobject ,and use .draggable() on it.

I tested swfupload & uploadify flash version,they show the same bug.

it seems that the bug only happens when it's a swf uploader.

mybe it only happens when swf bind some js callback,or need trigger some js event,or something.

the bug is in jquery's acceptData function:

  

   
acceptData: function( elem ) {
   
      var noData = elem.nodeName && jQuery.noData[ elem.nodeName.toLowerCase() ];
   
      // nodes accept data unless otherwise specified; rejection can be conditional
   
 return !noData || noData !== true && elem.getAttribute("classid") === noData;
   
}
  

mybe it should be changed to :

1. return !noData || noData !== true && elem.getAttribute && elem.getAttribute("classid") === noData;

here is my test case: http://jsfiddle.net/Niphor/ejLPk/
