8800	IE6-10: ENTER key immediately after an anchor generates javascript error	hel		"Assume the following content is within the ckeditor:
{{{
    Here is an anchor [anchor] in some text
}}}
where '''[anchor]''' is the anchor placeholder.

On IE9, if you place the cursor immediately after the anchor and then hit ENTER, it is possible to generate an ""Unable to get value of the property 'insertBeforeMe': object is null or undefined"" javascript error. See screen shot.

Also managed to recreate in one of the nightly build samples:
