Hmm... modes don't set themselves unless we ask for it (e.g. by using
`file-find-noselect` instead of `insert-file-contents`), so maybe
a better option is to change the code that causes the major modes to be
set so that it doesn't happen?
Binding `auto-mode-alist` to nil is not the end of the world, but it's
a kind of ugly hack and inevitably comes with undesirable side-effects
(e.g. any ELisp package that happens to be loaded during this time and
whose initialization code adds/removes entries from `auto-mode-alist`
will be affected).

Right. I don't see where a major is loaded in `org-export-to-file'.
Timothy, can you double-check the original error was not due to your
configuration? What happens with emacs -Q ?

Let's avoid this hack then. Thanks!
