Dieter Maurer says it best:

  In order to unindex objects later, Zope's indexes remember
  the values an object has been indexed by.

  "KeywordIndex" is a bit stupid about this.
  If the sequence contains duplicates, it does not remove
  them.
  Later, when the object is unindexed, it tries to remove
  the object from the list for each term in the sequence.
  In case of a duplicate, this goes well when it is
  encountered for the first time but, when it is encountered
  again, the object can (of course) not be removed...

Our fix makes sure that duplicates don't get into 
the list in the first place.

We're including 2 patches for 2 versions of Zope: 

 KeywordIndex.py.patch-251
 KeywordIndex.py.patch-261
