tdenetworkmanager serious problem with WPA2 Enterprise

Hi I can connect without problem to my private net, via WPA personal, however when I try to connect to WPA2 Enterprise I cannot save my settings, I receive Can't save Potential causes: * Insufficient permissions * NetworkManager not running * DBUS failure Of course I cannot connect since the setting is not saved. What puzzles me is that WPA Personal is fine. I consider the failure for WPA Enterprise as a serious bug and I know it did not happen for example in Ubuntu 10.04+relevant trinity version. Any help would be strongly appreciated. Uwe Brauer
