I think this is probably what Chris is referring to in his workaround
suggested today. Certainly I have no headers in my accounts table apart
from the one the I added (at the end) for testing.
I'm about to add a header at the start, dump a new test copy of the
database and try again.
What is the reason for the header association constraint in the
migration code? I have to admit that I never saw any reason for header
accounts, but that is probably my lack of understanding
