Document has invalid structure V4R5 AS/400 - Domino 5.0.4a - DECS to DB2

I have a bunch of documents that I have created into a Domino database via
an Agent doing a data load.
I need to change the value of a field on some of the documents, again using
an Agent.  
When the change agent does the save method after changing the necessary
field,  I get a
         'Notes Error: Document has invalid structure'    message and the
agent dies.

After getting this message I tried to copy the database to a new database
and copy the records, and I get the same message once the database design
has been copied.

Is there something that I am not doing to the documents when I load them
with the Agent ??
Is there something that needs to be done to the document that I am changing
with the agent ??

Any ideas are welcome ??
