Finally I've some time to look at this. Can you still reliably reproduce
this every time? I think it happens only when some specific fields are
cached. If the mailbox itself doesn't contain anything sensitive, could
you send it to me along with its index files? Alternatively I'd like to
see the cache fields output of "doveadm dump ~/mail/.imap/mailboxname",
e.g.:

-- Cache fields --
 #  Name                                         Type Size Dec  Last used
 0: flags                                        bit     4 tmp  2010-05-31 19:53
 1: date.sent                                    fix     8 no   1970-01-01 01:00
