Subject: ActionMailer PDF attachment and Windows

I've been struggling for a couple of days down with trying to attach a
pdf file to an email using ActionMailer on Windows.  All the examples
on the web I could find instructed me to use ":body => File.read
(<filename>)" to do the attachment.  The attached file was always
corrupt.  I attempted to simply copy the file using File.read
(<filename>), and the copy too yielded a truncated file.

What just now worked for me was a different body syntax.  What works
is the following:  ":body => File.new(fattach,'rb').read()".  I don't
exactly understand the significance of the of the difference.  Nor do
I understand why the original example above works in Linux but not
Windows, and why the latter example works in Windows.  But it does
work.  I just want to get discussion on the web in case someone else
encounters the same problem, and this provides an alternative
solution.

class Emailer < ActionMailer::Base
  def report_attachment(to,cc,bcc,from,subject,body,fattach)
    pp to,cc,bcc,from,subject,body,fattach
    recipients to
    cc cc
    bcc bcc
    from from
    subject subject
    body body

      attachment :content_type => "application/pdf",
        :content_disposition => "attachment",
        :filename => File.basename(fattach),
        :body => File.new(fattach,'rb').read()

  end
end
