wpa_supplicant-upplicant network down

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -ddd reports the following 
error:


[...]

My config-file is really simple:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

# ap_scan=1

# home network; allow all valid ciphers
network={
        ssid="secret"
        #scan_ssid=1
        key_mgmt=WPA-PSK
        psk="very secret"


Any ideas? On my older debian notebook this config worked without problems, 
the same card in my gentt notebook refuse to work.
