Purchase Order report does not print destination address

When Purchase Orders (POs) are printed the "Ship To" destination address is not printed. The address prints in the request for quotation report (request_quotation.rml) however nothing appears in the PO report (order.rml).

To reproduce this I print a Purchase order for either a Request For Quotation or Purchase Order from the GTK client (version 6.0.2 on Windows XP). In the resulting PDF I observe that the address is missing from the top left where I expect it to be.

The server is running OpenERP 6.0.2 on Ubuntu 10.04 LTS x86_64 with purchase module version 6.0.1.1

I expect that lines 175-182 from order.rml (shown below) should be printing the address.

  <para style="terp_default_9">[[ repeatIn(o.dest_address_id and [o.dest_address_id] or [],'addr') ]]</para>
  <para style="terp_default_Bold_9">Shipping address :</para>
  <para style="terp_default_9">[[ (addr.partner_id and addr.partner_id.title and addr.partner_id.title.name) or '' ]] [[ (addr.partner_id and addr.partner_id.name) or '' ]]</para>
  <para style="terp_default_9">[[ addr.street ]]</para>
  <para style="terp_default_9">[[ addr.street2 or removeParentNode('para') ]]</para>
  <para style="terp_default_9">[[ addr.zip or '' ]] [[ addr.city or '' ]]</para>
  <para style="terp_default_9">[[ addr.state_id and addr.state_id.name or removeParentNode('para') ]]</para>
  <para style="terp_default_9">[[ addr.country_id and addr.country_id.name or '' ]]</para>

However nothing in the cell is printed, not even the text "Shipping Address :" which I would expect to print even if the variables could not be found/accessed. This occurs on a new database (with rml files that have not been edited). Adding text in the cell did not show either, however it did appear when placed in the other cells surrounding this one. Also, if line 175 is removed then "Shipping address :" (from the next line) is printed but still no address.

Please let me know if you have any suggestions or need any further information.
