Network manager cannot read password for WPA2 wireless

[Lorenzo]

Binary package hint: network-manager

Ubuntu Karmic 9.10 - beta

libnm-glib2 0.8~a~git.20091005t192303.1d28ad1-0ubuntu2
libnm-util1 0.8~a~git.20091005t192303.1d28ad1-0ubuntu2
network-manager 0.8~a~git.20091005t192303.1d28ad1-0ubuntu2
network-manager-gnome 0.8~a~git.20091002t194214.8515a07-0ubuntu1

I select "connect to hidden wireless network."
I select "New connection"
I fill the required fields, (SSID authentication, password etc.)
The connection successfully goes up.

Shutdown - Reboot

I select "connect to hidden wireless network."
I select the connection i previously created (it is there)
The "password" field is empty and grayed out (as well as the "connect" button) [see attachment]
I check the keyring and the password is there, and it is the correct one.
No error or info in the logfiles.

If I remove the connection and add a new one, it starts (of course the problem return on the next reboot)

The bug does not occur with WPA/personal (i.e. WPA-PSK) but does happen with WPA2/Enterprise (office network).
