    Bug 787439 - Segmentation Fault in Transfer dialog after clearing...
    
     Date field and pressing escape.
    
    gtk_widget_destroy() ran the signals on the dialog controls which
    tried to access the XferDialog data, but since gnc_xfer_dialog_close_cb()
    had already run that memory had been freed and then used by the std::string
    in GncDate::format; later handlers attempting to access the XferData had
    garbage pointers to work with, causing a crash.
    
    Running gtk_widget_destroy() first preserves the pointers long enough for
    the dialog control callbacks to function without crashing.
