bug#29980: 11.90.2.2017-07-25; Failed to generate images of the preview

[韦星宇]

Remember to cover the basics. Including a minimal LaTeX example
file exhibiting the problem might help.

Greetings.

When I used Emacs to write my reports for a course with LaTeX, I found
that Emacs did not show the preview successfully. Then, I used the
following LaTeX file to check whether there was a problem:

\documentclass{article}

\begin{document}

\section{Formulas}
\[
E = mc^{2}
\]

\end{document}

It seemed that everything went well according to the log of the
previewing. However, since I enabled caching, I checked the temporary 
folder
and found a file named preview.dsc only. There should be a image file
(.jpeg), according to the log.

I tried to reinstall the ghostscript, since it is the last thing called
according to the log. However, the problem still exists.

Could anyone help me what should I check to solve this problems?

Thanks in advance.
