Comment 31 for bug 456468

surprisingly, i ran nm-applet from a command line and return this message:

root@douglas-desktop:#nm-applet

** (nm-applet:2560): WARNING **: <WARN> bus_init(): Could not get the session bus. Make sure the message bus daemon is running! Message: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Falló en GConf: Falló al contactar con el servidor de configuraciones; algunas de las posibles causas son que necesite activar TCP/IP en ORBit, o que tiene bloqueos de NFS debidos a una caída de sistema. Consulte http://www.gnome.org/projects/gconf/ para más información. (Detalles - 1: Falló al obtener la conexión con la sesión: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)
Ya existe una instancia de nm-applet en ejecución.

(nm-applet:2560): GConf-WARNING **: Directory `/system/networking/connections' was not being monitored by GConfClient 0x99626a8

and then run this command: "service network-manager"

root@douglas-desktop:#service network-manager
network-manager start/running, process 2566

and the network-manager icon appeared on panel...

I hope someone can help with this information
