[Zope] ZODB packing problem

[George Runyan]

when I try to pack my ZODB I get:

Error Type: KeyError
Error Value: 


Traceback (innermost last):

my ZODB doesnt pack, it remains 50.6M and after this error its still usable
(thank god).  now, is there any documentation on how to fix this?  when I
search for 'ZODB' I get a useless 341 items returned.  'ZODB
troubleshooting' I get 355 items.  :(  can someone point me to resources or
previous discussions?  

please help,
