To follow up on my own post and to help any others with this problem, I have 
found two ways of getting tooltips to work with Gtk::Toolbar:

The hack, which uses the Gtk::Tooltips object provided by Gtk::Toolbar -
  Gtk::Toolbar* toolbar_p = manage(new Gtk::Toolbar);
  Gtk::Tooltips* tooltips_p = Glib::wrap(tool_bar.gobj()->tooltips, false);
  Gtk::ToolButton* button_p = manage(new Gtk::ToolButton(image));
  button_p->set_tooltip(*tooltips_p, "Tooltips text");

Or the more kosher version which duplicates an unnecessary Gtk::Tooltips 
object -
  Gtk::Toolbar* toolbar_p = manage(new Gtk::Toolbar);
  Gtk::Tooltips* tooltips_p = manage(new Gtk::Tooltips);
  Gtk::ToolButton* button_p = manage(new Gtk::ToolButton(image));
  button_p->set_tooltip(*tooltips_p, "Tooltips text");

This seems to be a GTK+ rather than a gtkmm problem: C does not provide a 
proper access function for the GtkTooltips* member of struct _GtkToolbar.
