Comment 4 for bug 826331

so how the differences if you set "have file manager handle the desktop" to OFF on gnome-tweak-tool? on my oneiric, this option could hide the ugly nautilus's menubar from gnome-shell's desktop, but unfortunately unity-3d couldn't be loaded normally...

and gtk+3.0 had now applied advanced menu_proxy patches, on 3.1.10-0ubuntu3, but if we once rollback to 0ubuntu1, the issues solved!!
