IE Error "not enough storage is available..."

We recently upgraded to CKFinder 2.0.1 and found a new error appearing on IE:
"not enough storage is available to complete this operation".
We are using CKFinder in a couple of modes, one is JS integrated with CKEditor (version 3.2), as following:

CKFinder.setupCKEditor( null, { basePath : 'include/ckfinder/', skin : 'v1',ResourceType:'Files'});

In this case the error happens insize ckeditor.js

When we use CKFinder 2.0 directly with php interface like the following, we get the same error on IE in ckeditor.js

$finder = new CKFinder() ;
$finder->BasePath = 'ckfinder/' ;
$finder->SelectFunction = 'ShowFileInfo' ;
$finder->Create() ;

Everything works fine on Chrome / FF.
