Because you need to set up custom handlers before processing the glade
XML (they are used to construct widgets, which happens at
construction-time). Please update the FAQ -- and good catch.
This made me think that we might want to separate the parsing of the
tree into a separate method; something like:
self.tree = gtk.glade.XML("foo.glade")
self.tree.set_custom_handler(self.custom_widget_handler)
self.tree.parse()
Of course, this doesn't really follow GTK+.
