OK.  In the next step I'd like to isolate the menubar code as the sole
culprit for what's going in.  Please with master do

(setq default-frame-alist '((width . 200)))

or some other insanely large value so we can see whether we can make the
GTK error disappear this way.  And please apply the trivial patch
