[Twisted-Python] Trouble with example imap client on unread messages

[Andy Gayton]

I'm having trouble running Twisted/doc/mail/examples/imap4client.py on 
imap folders which have unread messages.  When the client issues:

proto.fetchSpecific('1:*',
	headerType='HEADER.FIELDS',
	headerArgs=['SUBJECT']
)

My server is returning:

  * 243 FETCH (BODY[HEADER.FIELDS ("SUBJECT")] {47}
  Subject: DELIVERY REPORTS ABOUT YOUR E-MAIL

  )
  * 244 FETCH (BODY[HEADER.FIELDS ("SUBJECT")] {42}
  Subject: AW: [syslinux] bug(?) in 2.11

  )
  * 244 FETCH (FLAGS (\Seen))

243 is a previously read message, 244 is an unread message.

The callback for the above fetchSpecific call is receiving:

{ 243 : [['BODY', ['HEADER.FIELDS', ['SUBJECT']], 'Subject: DELIVERY 
REPORTS ABOUT YOUR E-MAIL\r\n\r\n']], 244 : [['FLAGS', ['\\Seen']]] }

ie, I'm not getting the subject for unread messages.

Just wondering if this is a problem at twisted's end (is it incorrectly 
reducing the server response for 244 to [['FLAGS', ['\\Seen']]]?), my 
imap server (is it incorrect that my server is including the extra * 244 
FETCH (FLAGS (\Seen)) line ?  I'm using BincIMAP v1.2.12) or me :) (am I 
running something wrong here?)

cheers,
Andy.
