I am having the same problem with a custom workflow. Apparently it expects a user object, not simply a user name or email address. If I choose to send it to the creator, or tell it to use a people field it works fine. This is an important feature, as I need to be able to send emails to people that may not have an individual user name, since we are limited by the number of users allowed in the current hosting scheme unless we pay an addition $50/mo for all the email addresses we would need.
In the log files I am getting an error like so:
