Python httplib2, AttributeError: el objeto 'set' no tiene 'elementos' de atributo

Question

Juego con la biblioteca de Python httplib2. El siguiente es mi código.

import urllib.parse 
import httplib2 

httplib2.debuglevel = 1 

http = httplib2.Http() 

url = "http://login.sina.com.cn/hd/signin.php" 
body = {"act": "1", 
     "entry": "vblog", 
     "password": "P@$sW0rd", 
     "reference": "http://vupload.you.video.sina.com.cn/u.php?m=1&cate=0", 
     "reg_entry": "vblog", 
     "remLoginName": "on", 
     "username": "this_is_user_name", 
     "x": "", 
     "y": ""} 

headers = {"Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", 
      "Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7", 
      "Accept-Encoding", "gzip,deflate", 
      "Accept-Language", "en-us,en;q=0.5", 
      "Connection", "keep-alive", 
      "Content-Length", "181", 
      "Content-Type", "application/x-www-form-urlencoded", 
      "Host", "login.sina.com.cn", 
      "Keep-Alive", "115", 
      "Referer", "http://login.sina.com.cn/hd/signin.php?entry=vblog&r=http%3A%2F%2Fvupload.you.video.sina.com.cn%2Fu.php%3Fm%3D1%26cate%3D0", 
      "User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.16) Gecko/20110319 Firefox/3.6.16"} 

response, content = http.request(url, 'POST', headers=headers, body=urllib.parse.urlencode(body)) 

Cuando ejecuto, me sale el error:

Microsoft Windows XP [Version 5.1.2600]

C:\>python --version 
Python 3.2

    File "C:\Python32\lib\site-packages\httplib2\__init__.py", line 961, in request 
    headers = _normalize_headers(headers) 
    File "C:\Python32\lib\site-packages\httplib2\__init__.py", line 184, in _normalize_headers 
    return dict([ (key.lower(), NORMALIZE_SPACE.sub(value, ' ').strip()) for (key, value) in headers.items()]) 
AttributeError: 'set' object has no attribute 'items'

Soy bastante nuevo en Python y httplib2, nada malo en mi código?

Gracias.

headers debería ser un diccionario, no un conjunto:

headers = {"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", 
      ...} 

Nota del colon en lugar de la coma.
