lyx-qt does not work in command line mode

[Loïc]

      Hello!
  I'm using  lyx-qt-1.3.0  (standard).
  I've been trying to execute commands such as
'lyx -e .... '  
 and get the error message  (more or less)
 'QFont : must create a QApplication before a QFont'

so....  I've backed to lyx-xforms, which works.
 
        Bye,
Loïc Teyssier
