Mail attachments not always recognized as present with tmail-1.2.7

Hello,

I'm hitting this bug with tmail-1.2.7 bundled within actionmailer-2.3.11 and HTML emails with embedded images sent from Apple Mail.app.

The thing is, TMail::Mail#has_attachments? gives false, but if I call #attachments, it returns the attached image correctly. Our problem ultimately, is that Redmine mail handler doesn't add attachments when creating or updating issues by mail.

Now where do I report this?

I gather that TMail was replaced with Mail in Rails-3.0, but we're running Redmine which is still on Rails-2.3. The rubyforge page (http://rubyforge.org/projects/tmail/) lists 1.2.3.1 as the latest version. Where does this 1.2.7 bundled with ActionMailer comes from?
