Hi there, I am sure offlineimap will become more robust over time. I am
not sure any changes so far will help you with gmail. I know that *I*
haven't focused on gmail. It's server implementation is a bitch.
Could it be that you are seeing

correctly deleted on the gmail side, but on subsequent runs are

Above 3 lines are not needed as set automatically. Just FYI.

You don't have an "INOBX." prefix or something?

OK, another theory. What I am sure about is that this occurs because
Gmail IS NOT AN IMAP SERVER, even if they like to call it this way!
You have realdelete=no. That means that if you delete something in
Thunderbird, it will likely "expunge" it from the folder the message was
in and put it into the local Trash folder.
However, when you "expunge" on the Gmail server with "realdelete=no", it
will merely remove the folder label on the google side and not really
delete the message. (is that really what you want to achieve with
realdelete=no?). I am not sure if it will put it into a Trash folder on
the Google side.
This behavior makes it very tricky to achieve proper IMAP syncing. IMAP
server have flags, so I am not sure why Google chose the approach it did
(perhaps because mail clients deal nicely with folders but only have
limited support for flags...).
Anyway, before I start rambling. Can you try the latest "next" branch
and see if you still see that behavior?
It contains a slight change in the syncing strategy, and if my hunch is
right (which I have not been very good at in articulating it,
sorry). Your behavior might not occur there.
That having said, the whole gmail support thing is still something I am
not very familiar with. It's a pity that it is so popular :-).

Fun, so we delete 143 msg on LOCAL, then copy over 11 messages from
GMAIL to LOCAL, then delete 11 messages on LOCAL then copy over 143 msg
From GMAIL TO LOCAL? ??? No wonder you exceed bandwidth. GMail's IMAP is
a pain, but this should never happen in any case.
Do try recent 'next' and tell me if you see a different behavior. I
might also need a more verbose log, if you are still seeing this.
