[AUCTeX] AUCTeX and Tramp

[Stephen Berman]

When I try to run LaTeX via Tramp on a remote file under AUCTeX, LaTeX
says it can't find the file.  I can't tell if this is a bug or a faulty
configuration or other user error.  I have the same LaTeX setup (paths,
etc.) on both the local and remote machines.  I can reproduce the
problem with Emacs -Q by evaluating (load "auctex.el" nil t t), opening
the file via /ssh:, and typing C-c C-c to run LaTeX.  Then I get the
following output:

LaTeX exited abnormally with code 1 at Mon May  5 15:19:25
-------->8---------

There's no problem running LaTeX on the same file under AUCTeX locally
on either machine, and there's no problem running LaTeX on the same file
via Tramp under the standard Emacs LaTeX-mode.  It's only the
combination Tramp+AUCTeX that fails.  I'd be grateful for any help
resolving this.

This is the setup on the local machine (but I get the same behavior
using the Emacs 22.1 and AUCTeX 11.83 packages from openSUSE 10.3 on the
local machine; the remote machine only has the latter):
