I was trying to list messages deleted with

doveadm -f flow -o mail_location=mdbox_deleted:/home/mail/xxxxxxx /mdbox fetch -u xxxxxxx "mailbox date.saved guid" ALL

And getting this error. What is this about?

doveadm(xxxxxxx): Panic: file mdbox-map.c: line 1494 (mdbox_map_get_uid_validity): assertion failed: (map->view != NULL) doveadm(xxxxxxx): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0xa192e) [0x7f854625592e] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f854625599a] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f85461e5257] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x61830) [0x7f854654c830] -> /usr/lib64/dovecot/libdovecot- storage.so.0(mdbox_update_header+0xa0) [0x7f8546551110] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x5d698) [0x7f8546548698] -> /usr/lib64/dovecot/libdovecot-storage.so.0(+0x5d7e0) [0x7f85465487e0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x44) [0x7f85465372d4] -> /usr/lib64/dovecot/libdovecot- storage.so.0(mailbox_sync+0x37) [0x7f8546537377] -> doveadm(doveadm_mail_iter_init+0x98) [0x55b4cd34c118] -> doveadm(+0x305b1) [0x55b4cd34a5b1] -> doveadm(+0x2bdcc) [0x55b4cd345dcc] -> doveadm(+0x2c9ca) [0x55b4cd3469ca] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x233) [0x55b4cd347823] -> doveadm(dovea! dm_cmd_ru n_ver2+0x50c) [0x55b4cd357fac] -> doveadm(doveadm_cmd_try_run_ver2+0x37) [0x55b4cd358047] -> doveadm(main+0x1e4) [0x55b4cd336214] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f8545e08555] -> doveadm(+0x1c605) [0x55b4cd336605] Aborted

Could be a bug, can you try running it in gdb with debug symbols installed and post bt full from gdb along with doveconf -n?

I am not really familiar with gdb. I found this in another thread, I hope this is ok.

yum install dovecot-debuginfo gdb

gdb doveadm

set args -f flow -o mail_location=mdbox_deleted:/home/popusers/xxxx/mdbox fetch -u xxxx "mailbox date.saved guid" ALL

run
