file completion bug

[sds]

GNU Emacs 22.0.93.2 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2007-02-05 on quant8

suppose I have a file ~/foozz/barzz/zot.c
 
C-c C-f foo TAB bar TAB zo TAB

==>

Debugger entered--Lisp error: (file-error "Opening directory" "no such file or 
directory" "/home/sds/barzz/")
  ad-Orig-read-file-name-internal("barn's/zo" "~/" t)
  read-file-name-internal("barzz/zo" "~/" t)
  all-completions("ratio/rs" read-file-name-internal "~/")
  PC-do-completion(nil)
  PC-complete()
  call-interactively(PC-complete)
  read-file-name("Find file: " nil "~/" nil)
  find-file-read-args("Find file: " nil)
  call-interactively(find-file)


note that after each TAB, only the latest dir name appears in the
minibuffer, i.e.:

~/foo TAB ==>
foozz/

foozz/bar TAB ==>
barzz/

barzz/zo TAB ==>
the above error.
