[Zope] KeywordIndex unindex_object could not remove documentId -928076309 from index keywords.

[Milos Prudek]

The error message in the subject appears in Zope stupid_log_file after 
upgrade from Zope 2.4.4 to Zope 2.5.1.

This is the full text of the error message:

2002-06-23T12:09:55 ERROR(200) KeywordIndex unindex_object could not 
remove documentId -928076309 from index keywords.  This should not happen.
Traceback (innermost last):
   File 
/usr/local/Zope-orl-new/lib/python/Products/PluginIndexes/common/UnIndex.py, 
line 168, in removeForwardIndexEntry
     (Object: keywords)
KeyError: -928076309

Is this happening because the catalogs were exported from Zope 2.4.4 and 
imported to Zope 2.5.1 (along with all other objects)?
