I was having the opposite problem on 12.04 ... No power indicator applet (upon login -- saw one AT the login screen).
Running "gsettings list-recursively|grep settings-daemon" spat out that:
org.gnome.settings-daemon.plugins.power active false
...
In terminal, "gsettings set org.gnome.settings-daemon.plugins.power active true" ... logged out and back in and I was good.
This was a fresh install from ISO of 12.04, so for those of you seeing *two* icons, you might want to set "....plugins.power active false" and see if one goes away.
