Wrong CKFinder integration

I've written about trouble there: http://cksource.com/forums/viewtopic.php?p=49567#p49567
I've integrated CKFinder with CKEditor. CKFinder calls error (FF 3.6) when I press "Browse server". So I see empty window and error:
Error: !:@8?BC <http://core> >B:070=> 2 @07@5H5=88 =0 ?>;CG5=85 A2>9AB20 Window.CKEDITOR 87 <http://guard>.

String: 93
This string is a part of code:

         case 'ckeditor':
            var funcNum = get( 'CKEditorFuncNum' );
            if ( parentWindow['CKEDITOR'] ) //This is the 93 string!
            {
               config.selectActionFunction = function( fileUrl, data )
               {
                  parentWindow['CKEDITOR'].tools.callFunction( funcNum, fileUrl, data );
               };

               config.selectThumbnailActionFunction = config.selectActionFunction;
            }
            break;
