on_*() methods and wrapped objects

[Paul Pogonyshev <pogonyshev gmx net>]

Hi,

When I create a Gtk::ComboBoxEntry (actually, a wrapper over that),
on_changed() method on the entry seems to never be called.  However,
if I explicitly connect to signal_changed() on the entry, the handler
is invoked just fine.  Is it a known problem?  Do I do something wrong
or is there a workaround?  (Gtkmm is old, version 2.4.10.)
