sharing from gnome-control-center desn't work

[albocalbo]

when I try to switch on screen sharing, from file sharing or multimedia share immediately the user interface switch to off.
I suppose this happen because network manager can't enumerate the networks.
If I try to run gnome-control-center from shell I recieve the error

Failed to enable service vino-server: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Sharing cannot be enabled on this network, status is '0'

Finally if try to start vino server from shell everything it work

thank you

Did you ever get a solution for this? I have had the same issue for a while, and is a bit of an inconvenience.
