gnome-base/gnome-shell fails to load menu as it tries to load /etc/xdg/menus/applications.menu instead of /etc/xdg/menus/gnome-applications.menu.
How are you launching gnome-shell? We use /etc/X11/xinit/xinitrc.d/10-xdg-menu-gnome (installed by gnome-menus) to automatically set XDG_MENU_PREFIX to "gnome-" when DESKTOP_SESSION is "gnome" or "cinnamon" (which should be the case if you launch the gnome or cinnamon session from gdm or other modern login managers). Are you doing anything which might interfere with that setup, like custom /usr/share/xsessions files, unusual login managers, etc.? (On my system, with gdm-3.6.0, gnome-session-3.6.0, and gnome-menus-3.5.92, everything works as expected.)

I have unresolved yet problems with gdm-3.6 which I try to figure out (I thought that they might have common root cause but they don't). > We use /etc/X11/xinit/xinitrc.d/10-xdg-menu-gnome (installed by gnome-menus) > to automatically set XDG_MENU_PREFIX to "gnome-" when DESKTOP_SESSION is > "gnome" or "cinnamon" (which should be the case if you launch the gnome or > cinnamon session from gdm or other modern login managers).

Hmm. Gdm 3.5.9x/3.6.0 works for you (at least I have some data point it works for someone on Gentoo). Possibly having gnome-shell start from cmd would be helpful (it helps to find the debug the setup).
Current version from gnome overlay WFM (including gdm). It would be nice if it worked out of box from startx+gnome-session to debug issues.

Starting gnome-3 from the command line via startx never worked. You need to run all the scripts in xinitrc.d, you need to start a session bus, you need to register the session with consolekit or systemd, etc. Probably we should figure out the recommended way to do this and document it.
It is documented here: http://www.gentoo.org/doc/en/gnome-config.xml It might be a little bit out of date, but it is a start.
