nm-applet crashed with SIGSEGV in gtk_status_icon_set_visible()

[ToughBettina]

ubuntu 13.10 boots into user account but finishes with an empty launcher with message of internal error (since update today and demanded reboot). after recovery mode and repairing missing packages i ended up here (me not expert in ubuntu/linux, me spoonfed and fed-up user of winstupid and fairly new to linux but already learned of tons in shortest time)
