Hi,
I've installed Twisted 15.3.0 on Ubuntu 14.04LTS. Excellent work but there's
one problem bothering me for a long time:
twisted.mail.imap4.IMAP4Client.fetchMessage always throws exception and the
exception occured at random, e.g. somtimes the exception occured when the
program read the 120th mail, sometimes it occured at the 150th or 200th mail.
The traceback of the exception is as follows:
Unhandled Error
Traceback (most recent call last):

exceptions.ValueError: need more than 1 value to unpack
My code is as simple as possible and the exception is thrown by the following
codes:
dlist = []
for msg in messages: # use message number, not UID
d = self.fetchMessage(msg, uid=False)
d.addCallback(cbGetAttachment)
dlist.append(d)
dl = defer.DeferredList(dlist)
return dl.addCallback(cbLogout)
Is there anybody know about this issue?
