Then I suggest to take a look at the code in startup.el, starting
around line 1360, which is supposed to do what you expected.  From you
description, it sounds like something doesn't work there.  Stefan made
a change there 2 months ago, so if your previous version was before
that, maybe that change is the culprit.
