OK, so I tried this: 0. mkdir /tmp/emacs-bug 1. mv test.tex .emacs .emacs.desktop /tmp/emacs-bug 2. cd /tmp/emacs-bug 3. HOME=`pwd` emacs 4. M-x package-install RET 5. [Install auctex] 6. C-x C-f test.tex RET 7. And I see no crash. Are the above steps all that is needed? >> Could you also produce a backtrace of the problem?
