Yes, I'm archiving (or rather was) the NSImage. I wasn't aware of potential
problems and sure haven't had any reports on this going wrong in many years. I
guess it depends on what you do with the image, which is drawing into a context
in our case. Why does it conform to NSCoding if it's not safe to use?
Ironically the crash happens in a method used to get a PNG representation from
the image (see my reply to Mike) which we now save instead of the NSImage (to
save space and for platform compatibility of the archive between OSX and iOS).
