One crash issue

[Zhu Bicen <zhubicen gmail com>]

Below code can be compiled and launched successfully, but after exit it(by hitting the close button ) it crash.
VC++ 2005 express give me following info:

"Windows has triggered a breakpoint in LogLeader.exe.

This may be due to a corruption of the heap, and indicates a bug in LogLeader.exe or any of the DLLs it has loaded.
The output window may have more diagnostic information"

How to fix this? Any comments or advice is appreciated!

Thanks!


class LogListView : public Gtk::ScrolledWindow
{
public:
    LogListView();
    virtual ~LogListView(){}
private:
    Gtk::TreeView m_TreeView;
    Glib::RefPtr<Gtk::ListStore> m_refListStore;

    struct ModelColumns : public Gtk::TreeModel::ColumnRecord
    {
        Gtk::TreeModelColumn<Glib::ustring> group;
        Gtk::TreeModelColumn<Glib::ustring> code;
        Gtk::TreeModelColumn<Glib::ustring> timeStamp;

        ModelColumns() { add(group); add(code); add(timeStamp); }
    };
    ModelColumns m_columns;    
};
LogListView::LogListView()
{
    //create module
    m_refListStore= Gtk::ListStore::create(m_columns);

    //create treeView
    m_TreeView.set_model(m_refListStore);
    m_TreeView.set_rules_hint();
    m_TreeView.append_column("Group", m_columns.group );
    m_TreeView.append_column("Code", m_columns.code);

    m_TreeView.append_column("TimeStamp", m_columns.timeStamp);
    add( m_TreeView );   
    show_all();
}
class MainWindow : public Gtk::Window
{
public:
    MainWindow()
    {
        set_title("LoggerLeader");

        add( logListView_ );
        set_default_size(600, 500);
        show_all();
    }
    void on_button_quit()
    {
        hide();
    }

    ~MainWindow(){}
private:

    LogListView logListView_;

};
int main(int argc, char *argv[])
{
    Gtk::Main kit(argc, argv);
    MainWindow window;
