network manager shows passwords without verification

To Reproduce:
1) click network-manager-gnome icon and select "Edit Connections..."
2) Select a connection with a password and click "Edit"
3) Under the "Wireless Security" tab check "Show Password" to see the connection's password in plain text.

Network Manager should prompt for the user login password before showing the network connection's password.

Note this same behavior is in Passwords and Encryption Keys (seahorse) see Bug #189774
