If you just start a fresh session, save its desktop, then restart it,
while using the lazy-load feature, does it start normally? Maybe all
that's needed is to do this, with no personal files involved.

It would require me to explain too many things, so it won't be
efficient enough.

So do I, but it never crashes for me. Nor did we have such crash
reports until now. So there's something you do that I and others
don't, although I didn't mean (and didn't say AFAIK) that it's
something arcane.

Thanks.

Does Emacs crash when restoring a desktop file written by Emacs 24.5,
or only when it restores files written by Emacs 25?
