    mime-widget-text: Connect to the "pressed" signal
    
    Connect to the "pressed" signal of a GtkGestureMultiPress instead of the
    "button-press-event" widget signal.
    
    The HTML part context menu was the last user of an event signal.
    
    * src/balsa-mime-widget-text.c (mwt_gesture_pressed_cb), (bm_widget_new_html):
