[Bug-AUCTeX] 11.86; "TeX-insert-macro usepackage" crashes when cannot access directory

[Vangelis Evangelou]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report. In addition check if the bug is reproducable with an
up-to-date version of AUCTeX. So please upgrade to the version
available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your bug report will be posted to the AUCTeX bug reporting list.

Dear All,

The command \C-c\C-m usepackage crashes with the message

Searching for files...
Opening directory: permission denied, /maths/TeX/share/texmf-local/tex/latex/JCM

where
$ echo $TEXMFLOCAL
/maths/TeX/share/texmf-local:

I believe that a check should be made whether a directory is
accessible before attempting to search in it in order to avoid the
crash.
The expected behavior is to ask for a package name.
