I see that the commentary of frameset.el says it does not restore killed
buffers. That's fine, but a more informative error message would be
better ("Buffer 1 has been killed" or somesuch).

That comment refers to window-state-put's functionality, but this bug
is just that I forgot to check that the buffer was live before trying
to restore the point. Fixed now.

At that point, the saved state does not contain the buffer name, just
a marker that points nowhere, so we cannot say "Buffer XXX was killed"
because we don't know that it was called XXX. (Well, strictly speaking
the buffer name is probably somewhere inside frameset-states, but I
don't think digging that info is worth the effort.)

It already restores as much as it can, because that's what
window-state-put does. Dead buffers are ignored and their windows get
another buffer. The current bug does not happen when restoring the
window/buffer, just the selected buffer and point at the end of
jump-to-register.
Also, when using frame-configuration-to-register, jumping to a saved
frame configuration for a deleted frame fails silently. I don't think
jump-to-frameset should be noisier.
