Archiving emails in Gmail

[teja]

Hi,

I have a requirement that I want to log-in into a gmail account read
all unread mails, mark them as read and then archive them.
I am using libgmail (version 0.1.11) library to do so, using which I
am able to log-in into a gmail account fetch all unread message and
then read them one by one.
Now my problem is that I am not able to mark the unread mail as read
and archive it.

Below is sample code that I am using.


from libgmail import *

ARCHIVE_ACTION='rc_^i'  #the action string to archive a message
UNREAD_MAILS = "is:unread"

def ArchiveAll():
    ga = GmailAccount(name='username', pw='password')
    print 'logging in...',
    ga.login()
    print 'successful'

    def _getAllUnreadMails():
        return ga.getMessagesByQuery(UNREAD_MAILS, True)

    def _readMail(email):
        emailData = ga.getRawMessage(email)

    def _archiveAndMarkRead(email):
        ga._doThreadAction(ARCHIVE_ACTION, email)
        ga._doThreadAction(U_MARKREAD_ACTION, email)

    emails = _getAllUnreadMails()
    for email in emails:
        eData = _readMail(email)
        #Process email data
        _archiveAndMarkRead(email)

    print 'done'

if __name__ == '__main__':
    ArchiveAll()

after executing this code I am getting following error

HTTP Error 500: Internal Server Error
Traceback (most recent call last):
  File "test_libgmail.py", line 30, in <module>
    ArchiveAll()
  File "test_libgmail.py", line 26, in ArchiveAll
    [_archiveAndMarkRead(t) for t in sr[1]]
  File "test_libgmail.py", line 21, in _archiveAndMarkRead
    ga._doThreadAction(ARCHIVE_ACTION, thread)
  File "/home/3rdparty/libgmail/libgmail.py", line 669, in
_doThreadAction
    items = self._parsePage(_buildURL(**params))
  File "/home/3rdparty/libgmail/libgmail.py", line 383, in _parsePage
    items = _parsePage(self._retrievePage(urlOrRequest))
  File "/home/3rdparty/libgmail/libgmail.py", line 99, in _parsePage
    lines = pageContent.splitlines()
AttributeError: 'NoneType' object has no attribute 'splitlines'

Can anyone help me in figuring out what's going wrong here?
I guess google has deprecated this way of marking emails, correct me
if I am wrong here.
But if its true, is there any other way or library in Python to meet
my requirements?

Thanks in advance.
