simultaneous nm-applet

People, Is nm-applet supposed to work in two users logged at the same time? If it is, I have a problem here because only the first user logged in have the applet, the others get a error like this: [brunojcm@brunojcm-laptop ~]$ nm-applet ** (nm-applet:6195): WARNING **: <WARN> request_name(): Could not acquire the session service as it is already taken. Return: 3 ** (nm-applet:6195): WARNING **: <WARN> constructor(): Couldn't initialize the D-Bus manager. Is it a bug? Thanks in advance, -------- BrunoJCM
