Some related advice: stop shipping different versions of GNOME
software
in the same release. For example, Ubuntu GNOME 14.04 includes gnome-shell 3.10, gnome-settings-daemon 3.8, and
gnome-control-center
3.6. None of those are designed to work together: that's why you
have
control center panels displayed as if they were applications in the overview, and it's surely causing other bugs as well (I heard that suspend options were broken?).
Another: you have the Desktop folder displaying in the Places menu on nautilus sidebar; gnome-settings-daemon is supposed to tell GTK+ not to show that, but your gnome-settings-daemon is too old.
