Hi, Using dovecot v2.2.5.5, I get the following:
$ doveadm -v backup -R -u [email protected] maildir:/home/rsync/ example.com/user/Maildir/ [...] dsync([email protected]): Panic: file dsync-mailbox-export.c: line 228 (export_save_change_get): assertion failed: (change->type == DSYNC_MAIL_CHANGE_TYPE_FLAG_CHANGE) dsync([email protected]): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x59e6a) [0x7f91ad185e6a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f91ad185f2a] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f91ad144b89] -> doveadm [[email protected] Printing Quotes send:mailbox recv:mailbox](dsync_mailbox_export_init+0x8b8) [0x434028] -> doveadm [ [email protected] Printing Quotes send:mailbox recv:mailbox](dsync_brain_sync_mailbox_open+0x233) [0x42ba83] -> doveadm [ [email protected] Printing Quotes send:mailbox recv:mailbox](dsync_brain_slave_recv_mailbox+0x125) [0x42c615] -> doveadm [ [email protected] Printing Quotes send:mailbox recv:mailbox](dsync_brain_run+0x369) [0x42a929] -> doveadm [[email protected] Quotes send:mailbox recv:mailbox]() [0x42881b] -> doveadm [ [email protected] Printing Quotes send:mailbox recv:mailbox]() [0x411ad7] -> doveadm [[email protected] Printing Quotes send:mailbox recv:mailbox](doveadm_mail_try_run+0x260) [0x4127a0] -> doveadm [ [email protected] Printing Quotes send:mailbox recv:mailbox](main+0x3f0) [0x4116c0] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed) [0x7f91acd8e76d] -> doveadm [[email protected] Printing Quotes send:mailbox recv:mailbox]() [0x4118bd] Other lines emitted were Info lines indicating what message was being processed. Unfortunately this appears to stop the backup dead in it's tracks. Suggestions on how to proceed? I was (originally) doing this as an IMAP to IMAP copy, and when that failed I managed to get the raw Maildir. Now I appear stuck with that too. Regards, Anand -- “Don’t be sad because it’s over.
