[sylpheed:36903] Re: Gmail throttling?

News from the frontlines:

The throttle seems now to have been put off my account, but when I
enter my Inbox via my main working instance of Sylpheed, it hangs
with the following in the Protocol log:

[13:14:19] IMAP4> 20 SELECT INBOX
[13:14:20] IMAP4< * FLAGS (\Answered \Flagged \Draft \Deleted \Seen $Forwarded $Junk $NotJunk $NotPhishing $Phishing JunkRecorded NotJunk Redirected)

[13:14:22] IMAP4> 22 UID FETCH 12966:39607 (UID FLAGS RFC822.SIZE RFC822.HEADER)

Does it mean that Sylpheed is trying to download most of me e-mail again?
