[gtkmm] gtkmm/gtk+ 1.2 Notebook bug (just for the records, I don't really expect a fix)

[Christof Petig <christof petig-baender de>]

There's a severe bug in gtkmm1/gtk+-1.2 integration when it comes to
destroying a notebook.

The notebooks switch_page signal is emitted after the notebook's
destructor is called. Here is a typcial backtrace :

#2  0x081625ea in Gtk::ProxySignal2<void, _GtkNotebookPage *, unsigned
int, Gtk::Notebook, _GtkNotebook, 0>::gtk_callback (p1=0x848b8d0, p2=1,
d=0x848bd20)
     at /usr/include/sigc++-1.0/sigc++/slot.h:456
[...]
#30 0x401b7baa in Gtk::Notebook::~Notebook () from
/usr/lib/libgtkmm-1.2.so.0

once you have connected switch_page to a virtual function, it repeatably
  crashes.

I will hack around this problem in glade-- (since I consider gtkmm1
obselete, too). [Remember: I still have to maintain gtkmm1 applications]
If you need a short (150 lines including comments) example, just tell me.
