I spoke too soon.  Adding "-u" mostly fixes the problem, but I've
just found an FTP server for which it doesn't fix it.

To reproduce:

Replace .emacs with the following:

-------cut-here-------8<--------cut-here--------8<-------cut-here-------
(setq tramp-default-method "ftp"
      ange-ftp-ftp-program-args '("-i" "-n" "-g" "-v" "-u")
      tramp-auto-save-directory "~/emacs/Tramp-Auto-Saves/"
      ange-ftp-send-hash nil
      debug-on-error t
      )

(defun f3 ()
  (interactive)
 (dired "/address@hidden:/"))
-------cut-here-------8<--------cut-here--------8<-------cut-here-------

and run Emacs like this:

  emacs -f f3

I see the following backtrace:

-------cut-here-------8<--------cut-here--------8<-------cut-here-------

Do you?

The *ftp address@hidden buffer contains the following:

230-  mirroring service for further and higher education. The JISC (see
230-  http://www.jisc.ac.uk) will no doubt make an announcement regarding a
230-  new service provider in due course.

Note particularly the line that says "fpwd".  The "f" of the "ftp>"
prompt was printed, then the "pwd" command was sent, and then the
"tp>" of the prompt was printed.  This happens every time.  If you
remove "ange-ftp-send-hash nil" from the .emacs then the "fpwd" line
becomes "fhash" instead, and the same backtrace happens.  Is this
what is leading to the "hash-table-p nil" error?

Chris.
