Title:
  wsgi.py "local variable 'options' referenced before assignment"

Status in OpenERP Server:
  Confirmed

Bug description:
  Getting a error when attempting to get connect via webdav.

  [2011-12-19 01:00:13,150][?] ERROR:werkzeug:Error on request:

  UnboundLocalError: local variable 'options' referenced before assignment

  
  It seems that /usr/share/pyshared/openerp/wsgi.py has a function that is inconsistent with the variable 'option', also referring to it as 'options'

  def return_options(environ, start_response):
      # Microsoft specific header, see
      # http://www.ibm.com/developerworks/rational/library/2089.html
      if 'Microsoft' in environ.get('User-Agent', ''):
          option = [('MS-Author-Via', 'DAV')]
      else:
          option = []
      options += [('DAV', '1 2'), ('Allow', 'GET HEAD PROPFIND OPTIONS REPORT')]
      start_response("200 OK", [('Content-Length', str(0))] + options)
      return []

  I've tested it by using 'options' and 'option', both remove the error
  I'm getting.  I'll leave it to someone who understands that section of
  code to make the appropriate choice of 'option' or 'options'
