Insert a smiley.
Drag and drop it somewhere in the document.
This bug is reproducible on Mac only. It doesn't happen on Windows.
As of FCKeditor 2.5 Beta, this one can be tested at http://www.fckeditor.net/demo.
Marking this bug as critical for FCKeditor.
Regressed in r21110.
The problem here is that we don't properly re-create fragments from web archives that have frames with about:blank URLs. I'm working on a fix.
I think that a workaround for FCKEditor would be to use complete URLs for smileys (currently, absolute ones such as "/fckeditor/editor/images/smiley/msn/regular_smile.gif" are used).

Seems OK. Maybe there's a more elegant way for us to make sure that "about:blank" is not treated as a base URL, but I can't think of anything off hand.
