My first reaction (I'll try to actually look at this) is that
something's referring to an NSDocument that existed before the
image was saved and is now indeed a "Dead Mac Pointer". What
I remember is that there was an issue related to holding on
to Hemlock buffers (that may refrence NSDocuments), but I
remembered other symptoms.
Dumb question: where does one find Bosco these days ? (Mikel's site
seems to be down.)
