Wiki Last Modified patch crashes RPC API page in .12

[txcraig]

When using this patch, I am seeing UndefinedError: "page" not defined after upgrading to Trac .12 with the latest XML RPC Plugin when accessing the API link (the XML RPC plugin adds a link to the top right to /rpc and that is the page with the error)

I solved it by wrapping the div in a py:if to check that page is defined:

<div py:match="div[@id='content' and @class='wiki']" py:attrs="select('@*')">
  <py:if test="page">
    <div class="lastmodified">Last modified by ${format_author(page.author)}, ${format_datetime(page.time)} (${dateinfo(page.time)} ago)</div>
 </py:if>
  ${select('*|text()')}
</div>
