Title:
  [Trunk/7.0] email_template crashes in send_mail if there is an
  attachment

Status in OpenERP Addons (modules):
  Confirmed

Bug description:
  If there is an email template with a report attached to it then this
  template crashes in send_mail() method.

  Steps to reproduce:

  1. Create a new database with demo data in it

  2. Install module 'Warehouse Management'

  3. Go to Settings/Users/Users and enable Technical Features for
  administrator

  4. Go to Settings/Technical/Email/Templates and create a new template:
  name: test template
  applies to: Picking List
  From: example@xxxxxxxxxxx
  To: example@xxxxxxxxxxx
  Subject: Example Subject
  in Advanced Tab select 'Picking List' as Optional report to print and attach

  5. Go to Settings/Technical/Actions/Server Action and create a new server action:
  Action name: Auto Send Email
  Object: Picking List
  Action Type: Python Code
  Condition: object.type == 'out'
  Python Code:
  template_obj = self.pool.get('email.template')
  tpl = template_obj.search(cr,uid,[('name','=','test template')])[0]
  template_obj.send_mail(cr,uid,tpl,object.id, True, context)

  6. Go to Settings/Technical/Workflows/Activities and edit activity named 'done' for Workflow 'stock.picking.basic':
  Change Server Action from empty to 'Auto Send Email'

  7. Go to Warehouse and create any delivery order to any customer

  8. Confirm and deliver the order. You'll see the error with the stack
  trace below.

  I traced it and it turns out the reason why it crashes is that send_mail() method iterates over attachments.iteritems() which implies that attachments is a dictionary.
  In fact the variable attachments is generated by generate_email() method where it is created as a list.

  Here is the stack trace:
