not writable

[Frank Doepper]

Hi,

some IMAP mailboxes are surprisingly changing to read-only when syncing.

(Using 6.3.5-rc1 now, fortunately the transaction is immediately aborted, 
so it can be completed at next try. In former versions the messages have 
been retransmitted and my work, consisting of sorting and deleting emails, 
was lost. Older version 6.2.0 worked seamlessly.)

It's almost reproducable, and I have a log snippet:

$ egrep -i 'read|writ|select|examin' ~/offlineimap-debug.log|grep woffs|grep -B40 -m1 writable

GJDD21 (Trash) gets opened READ-ONLY and GJDD22 (INBOX) gets opened 
READ-WRITE, but for some strange reason there seems to be a mistake.

Remote IMAP server is dovecot.

I would be glad if that could be fixed or at least explained. :-)

regards,
Frank.
