ActionMailer multipart messages with attachment rails3

Hi,

I try to send a multipart message with actionmailer under rails3.
When the mail client receives the mail the attachment is empty.
I do definitely attach a non-empty file.
Here is the code:

snip

recipients ["secret@secret.com"]
from "secret@secret.com"
subject "my subject"

attachments.inline['pict.png'] =
   File.read File.join(Rails.root, 'public/images/pict.png') #works fine

   part(:content_type => "multipart/alternative") do |p|
      p.part :content_type => "text/plain", :body =>
render("verwertung.text.haml")
      p.part :content_type => "text/html", :body =>
render("verwertung.html.haml")
  end

attachment :content_type => "text/csv",
           :filename => "verwertung.csv",
           :body => File.read('/tmp/verwertung.csv')

snip

The mail looks fine, e.g. the inline attachment is included, but the
attached file is empty!

What is the problem here?

Best regards,
Thomas

I did now
attachments['verwertung.csv'] = {:content => csv_content }

and it worked.
