Here is a little example...

I block switching to the Page 2, with your trick. The first time you select 
that page, the callback is called, but the page is not displayed. Good.

But then, if you click again on that page, the callback is not called 
anymore, until you switch to another page first (or just click on the 
current selected one). It acts like if this page was selected, but not 
displayed. Also note that if you click the currnt page again, the callback 
is not called neither. But is change internal stuff, as it calls the 
callback when clicking on Page 2!

Sounds like a bug to me...

import pygtk
pygtk.require("2.0")
import gtk

# Callback
def switchPage(widget, page, page_num):
    print "Page %d selected" % (page_num  + 1)
    if page_num == 1:
        notebook.stop_emission('switch-page')

# Create widgets
win = gtk.Window()
notebook = gtk.Notebook()
notebook.append_page(gtk.Label("Page 1"))
notebook.append_page(gtk.Label("Page 2"))
notebook.append_page(gtk.Label("Page 3"))
win.add(notebook)
win.show_all()

# Connect signals
win.connect('destroy', gtk.main_quit)
notebook.connect('switch-page', switchPage)

gtk.main()
