[#1425 Error when rating a wiki page in Plone 3.1.7]

When I try to rate a Wiki page, through the stars icons, I get the attached Traceback, instead of the page being rated and the stars updated.


Traceback (innermost last)::

  Module ZPublisher.Publish, line 202, in publish_module_standard
  Module ZPublisher.Publish, line 150, in publish
  Module plone.app.linkintegrity.monkey, line 21, in zpublisher_exception_hook_wrapper
  Module Zope2.App.startup, line 221, in zpublisher_exception_hook
  Module ZPublisher.Publish, line 119, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 42, in call_object
  Module Products.ZWiki.plugins.rating.rating, line 96, in vote
  TypeError

This can be fixed with this patch::
