In latex mode, when latex produces an error, sometimes using C-x `
(next-error) opens a dired buffer instead of jumping to the error.

Here is a file which reproduces it.

============ snip ==================
\documentclass[12pt]{article}

\usepackage{amsthm}
\usepackage{amsmath}
\newcommand{\polar}{x}
\newcommand{\oldlambda}{xx}

\begin{document}

 \begin{proof}
   
 \begin{align}
 g(\polar, s) &= \Re \phi(se^{i\polar})\frac{1}{4\pi}s
 \psi(i(\pi-se^{i\polar}),\pi-s) \\
 k(\sqrt{\oldlambda}, \polar, s) &= e^{
 \end{align}
 \end{proof}

\end{document}
================ snip ====================

Visit the file with C-x C-f emacs-tex-error.tex
Compile it with C-c C-f
Try to jump to next error with C-x `
You should find yourself in a dired session (at least that's what it
does for me), which is not useful.

Here is the output of latex, as it appears in the *tex-shell* buffer.

The parser finds this error and subsequently tries to determine the file
name.  In course of that it checks the "(\pi" construct with point right
before the backslash.  In this case the form
(file-readable-p (thing-at-point 'filename))
returns t and the file name is set to an empty string.  (This is what
`(thing-at-point 'filename)' returns.)

I'm not sure if this is a problem with `thing-at-point' or
`file-readable-p'.

As a workaround you could enable file:line:error messages for latex.

Ah, thanks for the suggestion.  I did not know about that feature.  That 
solves the problem for me.

Thanks for investigating this bug.

Looks okay (without actually trying it).  (I'd probably move the `setq'
call into the `string=' call.)  Of course it will still lose if there is
a string after the paren which corresponds to the name of an existing
file, but the chances for that are really slim.
