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.
