This is just warning saying that user settings provider (nm-applet) is not 
running. Should not cause problems.

This warning says that a connection you have configured is not correct, try to 
check the method of IPv4 setting (auto, manual, etc.).

I got this when trying to deactivate not active connection, because 
active_connection_path was empty.
So the command look like this:

dbus-send --system --print-reply --dest=org.freedesktop.NetworkManager 
/org/freedesktop/NetworkManager 
org.freedesktop.NetworkManager.DeactivateConnection objpath:

, which is not correct.
Run the script with 'bash -x <the_script>' to see issued commands.
