Yes, but how does that help us resolve this problem?  There's nothing
wrong in general with calling face-font, so linum-mode doesn't do
anything blatantly incorrect here.  It's just that this function is
called "too early" in the frame creation process.

How about adding some simple flag that would avoid calling
window-configuration-change-hook when adjust_frame_size is called from
x-create-frame?
