bug#69431: 30.0.50; Strange fontificaion behavior

[OGAWA Hirofumi]

I met the strange font-lock behavior,

# this doesn't work
    $ echo '* Foo' > a.org
    $ emacs -Q a.org

The above opens "a.org" as org-mode, but current emacs doesn't
fontificate the buffer properly for this.

But while reproducing this behavior, I noticed the following works as
expected.

# this works
    $ echo '* Foo' > a.org
    $ emacs -Q --eval "(provide 'dbus)" a.org

Thanks.
