Yast2 died with message qt frontend is installed but does not work

Hi Folks, Have recently installed SuSE v9.1 Prof. Everything was working fine. Installed Firefox (from SuSE rpm) and this seemed to break yast2 as when I now attempt to start yast2 it dies with the following message: warning: the qt frontend is installed but does not work warning: the ncurses frontend is installed but does not work You need to install yast2-ncurses to use the YaST2 text mode interface Attempting to start yast2 in text mode fails with the message: warning: the ncurses frontend is installed but does not work You need to install yast2-ncurses to use the YaST2 text mode interface The yast2-ncurses package is installed as is Qt. Any ideas as to what the underlying problem may be? Kind regards, Simon -- Simon JF Heaton Principal Technical Consultant Software AG UK Ltd.
