Comment 1 for bug 507835

Same bug here when trying to use WPA2 Enterprise with keys.

Package:
plasma-widget-networkmanagement (0.9~svn1029786+ag1-0ubuntu1) on karmic 9.10

Workaround:
disabling wireless connections in plasmoid and using wpa_supplicant works fine. Sample config:

<pre>
ctrl_interface=/var/run/wpa_supplicant
eapol_version=1

network={
               ssid="wpa"
               scan_ssid=1
               key_mgmt=WPA-EAP
               pairwise=CCMP TKIP
               group=CCMP TKIP
               eap=TLS
               identity="login"
               ca_cert="dir/wpaca.pem"
               client_cert="dir/wpauser.pem"
               private_key="dir/wpauser.pem"
               private_key_passwd="****"
          }
</pre>
