Please describe the problem:

I tried adding a ListViewText widget to my window. Everything works great except when the application quits. When I close the window, the program crashes. Crash location is a code block in gtkmm-2.4.dll. If I comment out the ListViewText lines it works fine but as soon as I add ListViewText, it'd crash on exit.



Steps to reproduce:
Hers is my code:

#include <gtkmm.h>

#pragma comment(lib, "glibmm-2.4.lib")
#pragma comment(lib, "gtkmm-2.4.lib")
#pragma comment(lib, "sigc-2.0.lib")
#pragma comment(lib, "atkmm-1.6.lib")

#include <windows.h>

using namespace Gtk;

#define LABELCTRL(N, L) class N##Label: public Label { public: N##Label():Label(L) {}} N;
#define TABLEATTACHSPAN(ROW, COL, ROWSPAN, COLSPAN, ITEM) attach(ITEM, ROW-1, ROW - 1 + ROWSPAN, COL-1, COL - 1 + COLSPAN);
#define TABLEATTACH(ROW, COL, ITEM) TABLEATTACHSPAN(ROW, COL, 1, 1, ITEM)

class MainWindow: public Window {
public:
	class MainLayout: public Table {

	public:
		LABELCTRL(lblUsername, "User name");
		LABELCTRL(lblIP, "IP");
		LABELCTRL(lblQuitMessage, "Quit Message");
		LABELCTRL(lblConnectionSetting, "Connection setting");
		LABELCTRL(lblPort, "Port");
		LABELCTRL(lblOptions, "Option");

		Entry entUsername;
		ComboBox cmbConnectionSetting;
		Entry entQuitMessage;
		Entry entPort;
		ComboBox cmbOptions;


		class IPEntryHbox: public HBox {
		public:
			Entry entIP;

			class btnConnectButton: public Button {

			public:
				btnConnectButton() : Button("Connect") {
					//set_size_request(1, 1);
				}
				
				bool on_button_press_event(GdkEventButton*) {
					return true;
				}

			} btnConnect;

			IPEntryHbox() : HBox(false) {
				pack_start(entIP);
				pack_end(btnConnect);
			}
		} ipInput;


		class serversListListViewText : public ListViewText {
		public:
			serversListListViewText() : ListViewText(2, false) {
				//set_column_title(0, "Server");
				//set_column_title(1, "IP");

				//set_size_request(400, 250);

				//insert_text(0, "asdf");
				//set_text(0, 1, "asdasdasda");
				
			}
			~serversListListViewText(){
				MessageBox(0,0,0,0);
			}
		} serversList;

	public:
		
		LABELCTRL(lblStored, "Stored");

		MainLayout():Table(10, 2, false) {
			TABLEATTACH(1, 1, lblUsername);
			TABLEATTACH(1, 2, lblIP);
			TABLEATTACH(1, 3, lblStored);
			TABLEATTACH(1, 4, lblQuitMessage);
			TABLEATTACH(1, 5, lblConnectionSetting);
			TABLEATTACH(1, 6, lblPort);
			TABLEATTACH(1, 7, lblOptions);

			TABLEATTACH(2, 1, entUsername);
			TABLEATTACH(2, 2, ipInput);
			TABLEATTACH(2, 3, serversList);
			TABLEATTACH(2, 4, entQuitMessage);
			TABLEATTACH(2, 5, cmbConnectionSetting);
			TABLEATTACH(2, 6, entPort);
			TABLEATTACH(2, 7, cmbOptions);

			//lblIP.set_size_request(100, 20);
		}
	} controls;

	//class: public Button {bool on_button_press_event(GdkEventButton * ) {Main::quit(); return false;}} btnExit;


	MainWindow() {
		//set_size_request(750, 550);
		add(controls);
		show_all();
	}

};

...

Main kit(&argc, (char ***) &args);
MainWindow mainWindow;
Main::run(mainWindow);


Actual results:
crashes on exit

Expected results:
expected it to quit peacefully

Does this happen every time?
yes
