Bug 24111

1) Enable the new infrastructure
2) Run gconf-editor
3) gconf-editor just sits there with a gray window

I assume gconf-editor will eventually come up, but I've never been patient enough to wait.  In attaching to it in the debugger, it seems to be repeatedly calling atk_object_ref_accessible_child at frame 27 below, though it seems to be done at about 1 second intervals.

If I disable the infrastructure, gconf-editor pops up very quickly.
