Well simply define in the C file a ml_gtk_html_init function that
calls gconf_init(), and declare it in gHtml.ml :

  external gtk_html_init : unit -> unit = "ml_gtk_html_init"
  let _ = gtk_html_init ()

But when does it segfaults ? Is it during the gtk_html_new or later
when you try to use the widget ? You could try to realize the widget
before using it (widget#misc#realize), that could trigger the creation
of the adjustements.
