  I got the same bug in five.grok. I struggled for a while, it is
  weird, because if you include the correct meta ZCML to have
  expressiontype defined, it still doesn't work.

  I fixed my problem with:

  <!-- ZCML of this package fails in Zope 2.13 for strange reason -->
  <exclude package="zope.contentprovider" />

  And including Products.Five. contentprovider were working
  like before afterwards.

  If you find a better solution, I would be happy to know it (reading
  Hanno reply makes sense).
