Ted Gould has proposed merging lp:~ted/dbusmenu/ordering-issues-again into
lp:dbusmenu.
Requested reviews:
DBus Menu Team (dbusmenu-team)
Most importantly this makes it so the GTK layer uses the realized count for
positioning the menu items instead of the absolute count to remove race
conditions of realization of menuitems. It also adds the ability to track
realization and some other warning cleanups and comments.

Your team ayatana-commits is subscribed to branch lp:dbusmenu.
