Workaroud: I solved this problem with tips showed here: http://ubuntuforums.org/showthread.php?t=1497083&highlight=panel+ages
I disabled the 3 services "gnome-keyring-daemon" preseted in Sistema (System) > Preferências (Preferences) > Aplicativos de Sessão (I don't know the name of this item in English). Then I created only one service "gnome-keyring-daemon" without any options. This solved my problem. According the link, it can be a problem with the gnome-keyring and the absence of the ubuntuone package (i uninstalled Ubuntu One because I did not need it). -- nm-connection-manager stalls - can't click on any button.
