GNOME images not displaying

[Steve Harrington <steven harrington verizon net>]

I'm having a problem getting the gnome stock icons to display.  Here is 
a simple XML file creating two buttons.  Both have an image on the 
button but only one of the images displays.  The program to display this 
GUI is also attached.  What am I missing?

XML:

<?xml version="1.0"?>
<interface>
<requires lib="gtk+" version="2.16"/>
<!-- interface-naming-policy project-wide -->
<object class="GtkWindow" id="Main Window">
<child>
<object class="GtkHBox" id="hbox1">
<property name="visible">True</property>
<child>
<object class="GtkToggleButton" id="togglebutton1">
<property name="visible">True</property>
<property name="can_focus">True</property>
<property name="receives_default">True</property>
<child>
<object class="GtkImage" id="image2">
<property name="visible">True</property>
<property name="stock">gtk-refresh</property>
</object>
</child>
</object>
<packing>
<property name="position">0</property>
</packing>
</child>
<child>
<object class="GtkToggleButton" id="togglebutton2">
<property name="visible">True</property>
<property name="can_focus">True</property>
<property name="receives_default">True</property>

</child>
</object>
</interface>
