Hi,

We have a Ubuntu 14.04 server with dovecot 2.2.9

If I try to run

/usr/bin/doveadm search -u email@exmaple.com mailbox Junk savedbefore 30d

It will dump a core file.

We have a similar config on an other server and there is no problem there.

Any ideas how to prevent the core dump?

Something goes wrong when opening "Junk" mailbox. Are you sure it exists? Can you doveadm with

doveadm -Dv search -u email@example.com mailbox Junk savedbefore 30d

There is public namespace defined. Maybe that is the problem?

You are right! It is OK that way.
