Regards,
Instead 'failed miserably' you should say what is the real problem ;)
And it is that the segmentation fault happens due to bad types of s_wireless
properties. SSID is not string but a byte array (it can generaly contain 0)
and the mode should be adhoc or infrastructure.
See corrected example in the attachment.

Re: Need help with the NetworkManager DBUS API
If you're trying to establish a connection while nm-applet is running then you have to add the connection information through gconf which nm-applet will pickup and create a new connection through NetworkManager.

RE: Need help with the NetworkManager DBUS API
I don't know whether this will help Anurup or not. I see that instead of using gconf, you can add the connections to the nm-applet via dbus.
