The only guess I have is that the correction had now enabled the :user-spec
key/attribute.  For a workaround I've change some lines of code in
lisp/dynamic-setting.el ... compare with the attached patch.

With this patch both the custom font if enabled in ~/.emacs as well as
the system font works here for GNU Emacs with GTK as well as with X11.
