I think I found a workaround, I copied login.keyring to 'default' and 'default.keyring' not knowing which one the nm-applet was looking for.
Then rebooted, and instead of the usual "Authentication Required By Wireless Network" window I got the "Keyring access needed" message windows on which I had the "automatically unlock keyring" checkbox.
I haven't had the time to verify but I think this might help.
