I created a simple content rule in my home space as follows:

If a MS Word document is added to my home workspace, send me an e-mail using the 'notify_user_email.ftl' email template.

If I add a document to the workspace, the following error occurs in the 'alfresco.log' file:
ERROR [org.alfresco.repo.action.executer.MailActionExecuter] Failed to send email to smartin
org.springframework.mail.MailPreparationException: Could not prepare mail; nested exception is java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
