You're using Rails 3, which uses JavaScript to issue delete requests. Because the request isn't set up properly, your log is showing Started POST instead of the correct Started DELETE.
The request will also not include the required CSRF data, and as of Rails 3.0.4 the session is silently reset instead of throwing an ActionController::InvalidAuthenticityToken error. This is why you suspect the authentication issue lies with Devise, but it is actually being triggered within Rails itself.
To fix this include the following in your layout:
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>
Also ensure you have an updated rails.js (which contains the JavaScript code used for delete requests). The Rails 3.0.4 upgrade notes explain the issue in more detail.
If you're using the jquery rails.js replacement, you can get the updated version from here.
