Very strange. The code sure looks right:
      switch (*p) {
      case 'u':
	quoted = g_shell_quote (inuri);
	g_string_append (str, quoted);
	g_free (quoted);
	got_in = TRUE;
	p++;
	break;
      case 'i':
	localfile = gnome_vfs_get_local_path_from_uri (inuri);
	if (localfile)
	  {
	    quoted = g_shell_quote (localfile);
	    g_string_append (str, quoted);
	    got_in = TRUE;
	    g_free (quoted);
	    g_free (localfile);
	  }
	p++;
	break;

That would be cool. Btw, this code is in libgnomeui, not in nautilus.
