I'm guessing this isn't good ;-) What does that KeyError mean?
What would be the suggested way of proceeding?
That happened to me once. It was a plone site, with two ZODB's, one
mounted on top of another. I had an archetype content type that had a
FileField, but I had forgotten to set 'NonEmptyFile' as validator for
the field, and some default object (I think it was an empty list []) was
being set for all content objects with no file attached. The same empty
list for all content objects. I moved some of those objects from one
ZODB to the other, and then, when trying to pack, I would have that
error. The reference type 'n' is (from ZODB/serialize.py):
'n'
Multi-database simple object reference. The arguments consist
of a databaase name, and an object id.
the empty list was referenced from multiple databases.
there is some discussion about this issue here:

What I did was to walk through all objects in the database removing the
empty files, and then packing was possible.
Hope that helps.
