Trying to convert ethereal to curses I have stumbled on this
problem, in get_column_format if the clp value is null a 
segmentation violation is generated.  I admit this is an 
unusual situation.  However I think a simple sanity check here
could avoid the segmentation violation and either terminate
the program with an error or generate an assert message. 

gint
get_column_format(gint col) {
  GList    *clp = g_list_nth(prefs.col_list, col);
  fmt_data *cfmt;

/*$$$ need to test for clp = 0 here and handle it or quit */
  cfmt = (fmt_data *) clp->data;

  return(get_column_format_from_str(cfmt->fmt));
}
