Gmail Imap RFC822.SIZE fail (zero)

I’m working on my BackUp Gmail App for OSX and I got a very strange issue.

This is the Imap transaction on Gmail server:


>> TAG02 UID FETCH 77480:77490 (UID RFC822.SIZE RFC822 X-GM-MSGID)


<< * 22136 FETCH (X-GM-MSGID 1384367682512034576 UID 77480 RFC822.SIZE 0 RFC822 {11012}
Delivered-To: *****@gmail.com
....
....
....
)
TAG21 OK Success

Look at the RFC822.SIZE, it’s 0 (zero)!
But it isn’t really zero because then it starts the RFC822, and it’s complete (11012 bytes).

When I create the backups I got it always at the same time, all the emails after Nov 2011 until Feb 2012 have this issue.
Maybe Gmail had problems in this period?
Anybody knows it?

I posted this issue on the Imap-protocol mailing list and today I received a reply from Jamie Nicolson (Google).
As you can read in this reply it is a temporary Gmail bug: “it affected messages during a certain timeframe in the past … We’re hoping to clean this up”.
