I am having the problem too. It manifests in the form described by David; when i connect to my WPA2 network for the first time (after purging the essid from gconf), I enter the key and connect. Any subsequent attempt fails with
NetworkManager: <WARN> nm_utils_supplicant_request_with_check(): real_write_supplicant_config: supplicant error for 'SET_NETWORK 0 psk <key>'.
