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 with GNU Emacs 23.0.60.3 (i686-pc-linux-gnu, GTK+ Version
2.12.0) of 2008-05-05 on escher
