Since Glib::ListHandle doesn't work for me, I tried using a normal STL 
container instead:

void FileBrowser::on_selection_changed()
{
    std::list<Gtk::TreeModel::Path> selected_rows  = 
m_tree_selection->get_selected_rows();

    std::list<Gtk::TreeModel::Path>::reverse_iterator riter = 
selected_rows.rbegin();

    m_last_row = *( m_model->get_iter( *riter ) );
//    m_tree_selection->selected_foreach_iter( sigc::mem_fun( *this, 
&FileBrowser::selection_callback ) );
}

This compiles, but the program crashes.
