Updates broke dbus? -- Method "getVPNConnections" with signature "" on interface "org.freedesktop.NetworkManager.VPNConnections" doesn't exist

[Miles Lane]

This morning NetworkManager stopped working.  It seems that one of
yesterday's updates broke something?

** (nm-applet:5464): WARNING **: <WARNING>      
nma_dbus_vpn_update_vpn_connections_cb (): dbus returned an error.
  (org.freedesktop.DBus.Error.UnknownMethod) Method
"getVPNConnections" with signature "" on interface
"org.freedesktop.NetworkManager.VPNConnections" doesn't  exist
