libgmail login() runs with error

I just insta开发者_运维知识库lled libgmail on CentOS 5, python 2.6 with easy_install. There was a problem, until i installed mechanize manually. After that easy_install said OK and i wrote 1st test program from the sample i googled:

    import libgmail

    ga = libgmail.GmailAccount("someaccount@gmail.com", "mypassword")
    ga.login()
    folder = ga.getMessagesByFolder('inbox')

    for thread in folder:
      print thread.id, len(thread), thread.subject
      for msg in thread:
        print "  ", msg.id, msg.number, msg.subject
        print msg.source

I get the following error message:

Traceback (most recent call last):
  File "gm.py", line 4, in <module>
    ga.login()
  File "build/bdist.linux-i686/egg/libgmail.py", line 305, in login
  File "build/bdist.linux-i686/egg/libgmail.py", line 340, in _retrievePage
  File "build/bdist.linux-i686/egg/mechanize/_request.py", line 31, in __init__
  File "build/bdist.linux-i686/egg/mechanize/_rfc3986.py", line 62, in is_clean_uri
TypeError: expected string or buffer

It seems, i get a problem not with my python code, but with libgmail installation. Any clues, anyone?

libgmail is deprecated and has stopped developing, since gmail started offering imap access.

Use imaplib or similar (twisted.mail comes to mind, example code here).
