[Stephane Perinelle]

When running simple (example) script I get UnicodeDecodeError: 'utf8' error: but that obvisouly depend on the source of message... Any idea on how to fix that?
Thanks a lot

<b>SCRIPT:</b>"
<i>
  import libgmail
  ga = libgmail.GmailAccount("XX@gmail.com", "XXX")
  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>
