Hi Maxim, Thank you to looking.

Yes, sourcing the current etc/profile fixes the issue. Therefore, EMACSLOADPATH should be the culprit and I had done a mistake, not enough investigating before reporting. My bad! Sorry! > I'll try to isolate how to reproduce the problem; if you have a way to > reproduce it I'm interested! I think it comes from the new EMACSLOADPATH variable. The new Emacs binary is looking at it so if the etc/profile is not yet sourced then troubles arises. That's why it does not happen with "-Q" because no-site-file and no-site-lisp, i.e., EMACSLOADPATH is not "required". However, "-q" just turns off the ~/.emacs and needs EMACSLOADPATH. So I think to reproduce: install an old Emacs, upgrade, do not source again the current profile, launch Emacs from this profile. Well, it is not an issue but a bad practise. :-) Sorry. All the best, simon
