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

[Vangelis Evangelou]

Yes it does.

I believe you can reproduce the bug with the following commands in terminal:
mkdir -p $HOME/mytexmf/tex/latex/noaccess
chmod -rwx $HOME/mytexmf/tex/latex/noaccess
env TEXMFLOCAL=$HOME/mytexmf: emacs

And this is the backtrace information from emacs:
