23.0.50; View-quit: wrong-type-argument bufferp t

[Peter Dyballa]

Hello!

Launching GNU Emacs 23.0.50 from Wednesday or Thursday with -Q and  
opening from dired-mode a file (~/.alias) to view it, an error occurs  
when I quit the buffer with q:

        Debugger entered--Lisp error: (wrong-type-argument bufferp t)
          buffer-modified-p(t)
          kill-buffer-if-not-modified(#<buffer .alias>)
	  view-mode-exit(((#<window 3 on ~> nil #<buffer ~> 1 1033)) kill- 
buffer-if-not-modified)
          View-quit()
          call-interactively(View-quit nil nil)

Make it simple, as simple as possible but no simpler.
