slime, in order to get the lisp's output to go to an emacs buffer,
changes the followings bindings when starting up: *standard-output*,
*error-output*, *trace-output*, *standard-input*, *debug-io*,
*query-io*, *terminal-io*. so i think (this is a best a wild guess)
that the image is being saved with *error-output* bound to a broadcast
stream to an emacs buffer which doesn't exist when the image is
reloaded (or somethnig weird along those lines). try undoing the
stream redicetion before creating the image:
Ring the bells that still can ring.
Forget the perfect offering.
There is a crack in everything.
That's how the light gets in.
