Public bug reported: To reproduce: either start with a fresh Ubuntu install and then install xubuntu-desktop, or start with Xubuntu and then install ubuntu-desktop - ie have both Xfce and Unity installed on the same machine.
Xfce now has support for gtk3 indicators launched by upstart, but indicator-appmenu is totally broken - it will constantly crash the panel and applications. Xfce has a mechanism to hide indicators, and then the frontend UI will not be loaded in the panel, but it seems that UBUNTU_MENUPROXY is still being set in Xfce, which causes menus to disappear from applications, even though nothing is available to receive them. I discussed this with tedg and he suggested that the problem may be to do with the upstart service which sets UBUNTU_MENUPROXY, ie /usr/share/upstart/sessions/unity-gtk-module.conf We may in future get the appmenus working in Xfce, and then we would need some way to turn the menuproxy on and off depending on the user configuration. But for now, since they are broken anyway, it would be easiest to simply blacklist xubuntu desktop completely.
