Cannot execute encoding commands

[Eric Knauel]

I'm trying to use tramp (version "$Id: tramp.el,v 2.95 2002/04/10
17:16:25 kaig Exp $") to connect to a FreeBSD 4.6.2 machine using the
"su" (ssh + uuencode) method. This fails, because tramp can not
execute de/encoding commands -- which is strange, since uuencode in
the PATH on the local and remote machine (/usr/bin). I couldn't figure
out what tramp is trying do here and why it raises this error. Judging
from the Lisp backtrace, it doesn't seem to run uuencode at all:

buffer `*tramp/su address@hidden' for details")

|   call-interactively(find-file)

Unfortunately, the buffer doesn't contain more details:

,----[ *tramp/su address@hidden ]
| 
| Process *tramp/su address@hidden killed
`----

Here is my setup:

,----[ ~/.xemacs/init.el ]
| (let ((tramp-dir (expand-file-name "~/.xemacs/lisp/tramp")))
|   (if (file-accessible-directory-p tramp-dir)
|       (progn
|       (setq load-path (cons tramp-dir load-path))
|       (require 'tramp))))
| 
| (setq tramp-verbose 10
|       tramp-debug-buffer t
|       tramp-default-method "su"
|       shell-prompt-pattern "\\(#\\|\]\\) $")

Now I'm really confused! ;-)
