BTW, there's no easy way to revert the problematic commit, in view of this commit, which came on the next day: http://git.gnome.org/browse/glib/commit/?h=glib-2-32&id=1c8c408c51c85230356cc95c06f2e1bd3f376624 The commentary that goes with that commit gives some explanations of what's supposed to happen. It doesn't mean much to me, because of my ignorance of how glib works. But maybe it will give you an idea where to look.
