Binary package hint: xfce4-indicator-plugin

xubuntu installed 11.04 alpha 2on sun 27th feb. 20:00 and updated it till 21:00 with auto-updater and also with terminal
apt-get update, apt-get dist-upgrade same problem. no user-name or button in panel for the session manager and also no button in the panel for network-manager. both "places" are click-able and it's possible to logout or connect to a network. but it's really hard
