Network Manager changes between Ubuntu 9.04 and 9.10.

[Chris Hessing <chris hessing cloudpath net>]

I have some code based off the script from 
http://osdir.com/ml/networkmanager-list/2009-07/msg00035.html that is 
used to add a system level connection to the configuration on a 
machine.  It worked great on Ubuntu 9.04.  However, in Ubuntu 9.10, I am 
getting the error :

org.freedesktop.DBus.Error.UnknownMethod: Method "AddConnection" with 
signature "a{sa{ss}}" on interface 
"org.freedesktop.NetworkManagerSettings.System" doesn't exist.




This error comes out of the script from the URL above.  The same script 
still works perfectly on Ubuntu 9.04.   Any hints on what changed?

Thanks!
