You guessed it! That's what happens.

Save the connection that is returned from
Glib::signal_timeout().connect() and use disconnect().

In Spin::Spin:
// m_connection is a sigc::connection.
m_connection = Glib::signal_timeout().connect(sigc::mem_fun(*this,
&Spin::on_timeout), m_Spin.get_value_as_int());
....
void Spin::on_spinbutton_digits_changed()
{
  m_connection.disconnect();
  m_connection = Glib::signal_timeout().connect(sigc::mem_fun(*this,
&Spin::on_timeout), m_Spin.get_value_as_int());
}
