We can on occasion (with an explicit selection, usually) have an image in the LookUp attributed string; we don't know how to serialize an attributed string with a image in it, though! In other cases, we round-trip through RTFD. This can lead to bizarre behavior with SVG, etc. (things that AppKit doesn't know how to render), but at least it doesn't crash anymore.
