Запустил приложение через gdb, вот что получил при падении:

//-----------------------------------------------------------------

В классе TableWindow есть поле
//-----------------------------------------------------------------
Glib::Dispatcher dispatcher_update;
//-----------------------------------------------------------------

В конструкторе класса TableWindow я присоединяю обработчик (метод TableWindow::on_dispatcher_update() ) к диспатчеру
//-----------------------------------------------------------------
   this->dispatcher_update.connect(SigC::slot_class(*this,
               &TableWindow::on_dispatcher_update) );
//-----------------------------------------------------------------

А потом в отдельном потоке пишу следующее, чтобы вызвать перерисовку таблицы:
//-----------------------------------------------------------------
w->dispatcher_update();
//-----------------------------------------------------------------

А вот и метод TableWindow::on_dispatcher_update()
//-----------------------------------------------------------------
void TableWindow::on_dispatcher_update()
{
    m_TreeView.queue_draw();
}
//-----------------------------------------------------------------

По-прежнему, не могу отыскать ошибку.
