[wx 2.6.2, GTK+ 2, GCC 4.1.0] Memory leaks

Hi, I started today with wxWindows. I get folowing example from a
tutorial. After that I run the program with valgrind and get folowing
output. It's a quite big memory leak for so simple program. Am I
forgetting to run some command or it is a failure of wxWindows?
Thanks Dan

#include "wx/wx.h"

class MyApp : public wxApp
{
public:
	virtual bool OnInit();
};

class MyFrame : public wxFrame
{
public:
	MyFrame(const wxString& title);
	void OnQuit(wxCommandEvent& event);
	void OnAbout(wxCommandEvent& event);
private:
	DECLARE_EVENT_TABLE()
};

DECLARE_APP(MyApp)
IMPLEMENT_APP(MyApp)

bool MyApp::OnInit()
{
	MyFrame *frame = new MyFrame(wxT("Minimal wxWidgets App"));
	frame->Show(true);
	return true;
}

BEGIN_EVENT_TABLE(MyFrame, wxFrame)
	EVT_MENU(wxID_ABOUT, MyFrame::OnAbout)
	EVT_MENU(wxID_EXIT, MyFrame::OnQuit)
END_EVENT_TABLE()

void MyFrame::OnAbout(wxCommandEvent& event)
{
	wxString msg;
	msg.Printf(wxT("Hello and welcome to %s"), wxVERSION_STRING);
	wxMessageBox(msg, wxT("About Minimal"), wxOK|wxICON_INFORMATION, this);
}

void MyFrame::OnQuit(wxCommandEvent& event)
{
	Close();
}

MyFrame::MyFrame(const wxString& title) : wxFrame(NULL, wxID_ANY, title)
{
	wxMenu *fileMenu = new wxMenu;
	wxMenu *helpMenu = new wxMenu;
	helpMenu->Append(wxID_ABOUT, wxT("&About...\tF1"), wxT("Show about
dialog"));
	fileMenu->Append(wxID_EXIT, wxT("E&xit\tAlt-X"), wxT("Quit this program"));
	wxMenuBar *menuBar = new wxMenuBar();
	menuBar->Append(fileMenu, wxT("&File"));
	menuBar->Append(helpMenu, wxT("&Help"));
	SetMenuBar(menuBar);
	CreateStatusBar(2);
	SetStatusText(wxT("Welcome to wxWidgets!"));
}
