Description of problem:
NetworkManager will only connect once to my WPA-Enterprise network. It presents
me the network form, on which I enter the authentication method, password and
certificate files and it then connects properly. But on all subsequent
connections, it fails (see log excerpt below) and I have to clean out the
contents of /system/networking/wireless/networks in gconf and restart nm-applet.

Usually I'd expect to be presented with a dialog prompting me to unlock the
keyring for the certificate password, but I'm not. I've checked with
gnome-keyring-manager that the relevant key is present and that nm-applet can
access it.

Version-Release number of selected component (if applicable):
NetworkManager-0.6.5-3.fc7
gnome-keyring-0.8-1.fc7
ipw2200 driver

How reproducible:
Always.

Steps to Reproduce:
1. Clean out network info in gconf tree.
2. Connect to WPA-Enterprise network.
3. Disconnect.
4. Attempt to reconnect.
  
Actual results:
Connection fails.

Expected results:
Clean connection.

Additional info:
I get lots of log messages like
