The following is a proposal fix for the part of the code that is throwing the error:

+                               // only HTML.

+                               this.Elements[i] = node.removeChild( node.childNodes[1] ) ;
                        }
                }
        }

But then, there are still other things to get fixed to make it work.

Ok... apart from the weird IE bug in which you can't put a bare comment inside a node and expect it to appear in the DOM... there's also the issue that FCKeditor puts protected code as plain text into FCKTempBin, and those plain text should never be converted to DOM nodes at all.

Proposing a patch to fix both issues.

The proposed patch is ok. In my previously proposed patch I got also the chance with this fix to use removeChild to retrieve the final element so we release the reference to the temporary node. Couldn't it be used here too? (basically node.firstChild.removeChild( node.firstChild.lastChild ) at line 1118)
