python imap4client.py No secure authentication available. Login insecurely? (y/N) y [(('\\Noselect',), '.', '')]

Hi! I'm just trying to play with the imap4client.py example. but I've following problem: The mailbox name is "" and that seems to be a problem for twisted. I looked 1h to find the exact place of the bug, but couldn't find it. I hope now that someone on the list can point me on the line I need to change in order to make it work. I've used following code http://www.twistedmatrix.com/documents/current/examples/imap4client.py here the output of the client. the first list is from def cbMailboxList(result, proto): print result and the second list from: def cbPickMailbox(result, proto, mboxes): print mboxes 1. Which mailbox?
