Using Ubuntu 9.04, I can confirm this error. A VPN connection which worked in Ubuntu 8.10 gives this error/warning from nm-applet:
** (nm-applet:32714): WARNING **: Error in getting active connection 'Vpn' property: (19) Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist
** (nm-applet:32714): WARNING **: _nm_object_array_demarshal: couldn't create object for /org/freedesktop/NetworkManager/ActiveConnection/22
And nothing happens
