What version of glade-2 generated it ?

The problem with your glade file is that it is
missing the indicator that one of the labels
is the "label-item" of the expander, the expander
can hold one in the label area and one in the
area visible when expanded, like so:

        <packing>
          <property name="type">label_item</property>
        </packing>
