My usual workaround for that and related issues is never to run emacs
with -Q.  Instead I create an empty directory in /tmp and set HOME to
point there:

   HOME=/tmp/test emacs

I think that *could* be a much better behavior for emacs -Q even if it
means you can't access anything you normally reach via ~.
Another option of course would be to populate the test directory with
symlinks to make it look more like my home directory, but I actually
never needed anything like that.
