' This should not fail and, especially, Zope should not die.

' If Zope really dies, then there is a *severe* problem elsewhere

It does fail, however zope doesn't 'die', it merely fails, displaying an error
message. But as somebody else pointed out, it should read:

  <p tal:condition="obj/someAttribute|nothing"
     tal:replace="obj/someAttribute" />

because it's the tal:condition-tag that is failing. that's how I understand it
at least.
