Fix committed.  I've sent an email to release-team asking for somebody to roll
a new release.

------- Comment #3 from Paul Pogonyshev  2006-08-21 19:16 UTC -------
Here is an example from my program:

static void
gtk_goban_class_init (GtkGobanClass *class)
{
  static GtkUtilsBindingInfo navigation_bindings[] = {
    {GDK_Left,          0,      GOBAN_NAVIGATE_BACK},
    {GDK_Page_Up,       0,      GOBAN_NAVIGATE_BACK_FAST},
    {GDK_Right,         0,      GOBAN_NAVIGATE_FORWARD},
    {GDK_Page_Down,     0,      GOBAN_NAVIGATE_FORWARD_FAST},
    {GDK_Up,            0,      GOBAN_NAVIGATE_PREVIOUS_VARIATION},
    {GDK_Down,          0,      GOBAN_NAVIGATE_NEXT_VARIATION},
    {GDK_Home,          0,      GOBAN_NAVIGATE_ROOT},
    {GDK_End,           0,      GOBAN_NAVIGATE_VARIATION_END}
  };

  GtkWidgetClass *widget_class = GTK_WIDGET_CLASS (class);
  GtkBindingSet *binding_set;

  ...

  binding_set = gtk_binding_set_by_class (class);
  gtk_utils_add_similar_bindings (binding_set, "navigate", navigation_bindings,
                                  (sizeof navigation_bindings
                                   / sizeof (GtkUtilsBindingInfo)));
}

/* Elsewhere. */
void
gtk_utils_add_similar_bindings (GtkBindingSet *binding_set,
                                const gchar *signal_name,
                                GtkUtilsBindingInfo *bindings,
                                int num_bindings)
{
  int k;

  g_return_if_fail (binding_set);
  g_return_if_fail (signal_name);
  g_return_if_fail (bindings);
  g_return_if_fail (num_bindings > 0);

  for (k = 0; k < num_bindings; k++) {
    gtk_binding_entry_add_signal (binding_set,
                                  bindings[k].keyval, bindings[k].modifiers,
                                  signal_name,
                                  1, G_TYPE_INT, bindings[k].signal_parameter);
  }
}

Note that you are done with using gtk_binding_set_by_class() and
gtk_binding_entry_add_signal().  Everything else is just utility for my own
use.
No special handling of the created binding set is required, it is automatic in
the sense that it is handled by GTK+ itself.

------- Comment #4 from Paul Pogonyshev  2006-08-21 19:29 UTC -------
However, there are two difficulties I can see for a C++ implementation.  First
is that standard usage of GtkBindingSet relies on GType and, as far as I
understand, all Gtk::Widget descendants will have one GType in a Gtkmm program.
 This may be solved with `typeid'.

Second is that GtkBindingSet uses C-level signals and I'm not sure how to use
C++-level (sigc++) signals instead.
