Hi there, it is OK for us to sometimes select a folder as RO (we do that
e.g. when we cache messages status.) and sometimes as RW. However, what
seems to be happening here, is that we are trying to select the inbox,
and the server responds with OK. I don't know where the error "ERROR:
Server 'imap.gmail.com' closed connection, error on SELECT
'INBOX'. Server said: INBOX is not writable" is coming from.

I have never seen that error myself.

I have now pushed the following commit to both my next and master
branch, which might help fix things, at least it makes things more
correct in any case. Does current master on my git repository
(git://github.com/spaetz/offlineimap.git) make things work?

    Fix mbox.select(foldername) readonly parameter comparison
    
    The default parameter value was "None", and we were comparing that
    directly to the imaplib2 value of is_readonly which is False or True, so
    the comparison always returned "False".
    
    Fix this by setting the default parameter to "False" and not
    "None". Also convert all users of that function to use False/True.
