As Ethan said, the release you are using doesn't yet support access to
defined variables in python.

Instead, try the following:

  <div tal:define="ui python:container.userInfo()">
    <b tal:replace="ui/dn">crap</b>
    <b tal:replace="ui/sn">crap</b>
    <b tal:replace="ui/cn">crap</b>
  </div>

It will be much more readable, and it removes a layer of interpretation
too.
