guile-1.5.1, gtk crashes

[David Pirotte]

hi,

is there anything i can do to get more info on the following
crash?

the code was running perfectly using guile-gtk, but does not run
above guile-1.5.1 using (gtk gtk):

        #!/usr/local/bin/guile -s
        !#
        
        (define-module (alto tactus rent)
          ...
          :use-module (gtk gtk)
          ...
          )

        (define (rent/gui . rest)
          ...
          (gtk-standalone-main window)
          )
        (rent/gui)
                

        address@hidden:~/ 10 $ ./rent.scm 
        Gdk-ERROR **: Fatal IO error 0 (Succès.) on X server :0.0.
        address@hidden:~/ 10 $
