409 Conflict when updating contact w/o changes

I'm using the v2 api via the ruby sdk.  When calling update_contact with an unchanged contact, I receive a 409 Conflict error

client = ConstantContact::Api.new(
  ENV['CONSTANT_CONTACT_KEY'],
  ENV['ACCESS_TOKEN']
)

contact = client.get_contact_by_email('[email protected]')
client.update_contact(contact)

This only happens to a few contacts.  How can I figure out the conflict so I can update existing contacts?
