Comment 16 for bug 664731

dbusmenu provides a facility for global menus, it's developed by Canonical for Ubuntu but freely available for other OS's. Gtk and Qt support it, but LibreOffice will need an additional patch to do so. A quick review of LibreOffice menus suggests it doesn't use anything that is not already provided by dbusmenu, it should simply be a matter of connecting the dots.

Am filing this bug here to facilitate coordination of a fix, as the issue has been reported in the Ubuntu bugtracker.
