Hi, 

This is a strange behavior which was not happening in previous versions
of emacs. Though quite an unusual use, I decided to report it as it
might be a symptom for a more serious problem.

Create a buffer "test.tmp" and create an indirect buffer:
   
   (with-current-buffer (make-indirect-buffer "test.tmp" "test1")
     	    (add-hook 'kill-buffer-hook
   		      '(lambda ()
                            (setq kill-buffer-hook nil)
                            (kill-buffer (buffer-base-buffer)))
   		      t t))

(The above triggers the killing of the base buffer when an indirect
buffer is killed)

Now, kill the base buffer "test.tmp", which raises:

  signal(error ("Buffer #<killed buffer> is not a live buffer"))
  error("Buffer %s is not a live buffer" #<killed buffer>)
  window-normalize-buffer(#<killed buffer>)
  replace-buffer-in-windows(#<killed buffer>)
  kill-buffer(#<killed buffer>)
  (if (and (boundp (quote sub-kill-buffer-and-its-windows)) sub-kill-buffer-and-its-windows (fboundp (quote kill-buffer-and-its-windows))) (kill-buffer-and-its-windows (current-buffer)) (kill-buffer (current-buffer)))

This doesn't occur when killing an indirect buffer.
