Add Lead via Webform API (wufoo)

I am getting error code 4600 - and I can't track down where the error is coming from.

Here is the response:

<?xml version="1.0" encoding="UTF-8" ?>
<response uri="/crm/private/xml/Leads/insertRecords"><error><code>4600</code><message>Unable to process your request. Please verify if the name and value is appropriate for the "xmlData" parameter.</message></error></response>

Here is the XML generated from the form submission:

<Leads><row no="1"><fl val="Company">Test Company</fl><fl val="First Name">John</fl><fl val="Last Name">Doe</fl><fl val="Title">owner</fl><fl val="Email"> john@doe.com</fl><fl val="Phone">123-456-7890</fl><fl val="Street">1234 Main St #4</fl><fl val="City">Dallas</fl><fl val="State">TX</fl><fl val="Zip Code">75206</fl><fl val="Country">United States</fl><fl val="Website"> http://www.website.com</fl><fl val="Description">New Lead from Website</fl><fl val="Lead Source">Retailer Registration Form</fl><fl val="Lead Owner"> owner@website.com</fl></row></Leads>nn

Anyone see an obvious error?

The form is submitted properly to wufoo, and the record generated, and the email notification is sent.
