There's a note in the GTK+ documentation [1] that states:
Prior to 2.20, GtkBuilder was setting the "name" property of constructed
widgets to the "id" attribute. In GTK+ 2.20 or newer, you have to use
gtk_buildable_get_name() instead of gtk_widget_get_name() to obtain the
"id", or set the "name" property in your UI definition.
So, in your case the following works:
label = bld.get_object('label1')
print gtk.Buildable.get_name(label)
I have no idea why Glade saves the value of the "Name:" field from
the "General" tab as a gtkbuildable object id instead of a gtkwidget
name, but maybe it's related to the "Object names are unique (withing
the project||inside toplevels)" setting...
mvg,
