I've replaced notebook with simple frame container. Problem is still there.
I am going to bug this issuse.

There is no memory leak. When I do remove_page() ( 
gtk_notebook_remove_page() ) from notebook that function does free child 
widget automatically.

I found the solution: you have to call hide() and show() for toolbar 
widget just after reparenting.

toolbar->hide();  // ( gtk_widget_hide( toolbar ); )
toolbar->show();  // ( gtk_widget_show( toolbar ); )
