It also happens if I only telnet to the imap(s) port and give the only command "1 logout".

Then it should be easy:

1. telnet localhost 143
2. gdb .../dovecot/imap-login <pid of imap-login process> cont
3. logout to make it crash
4. gdb: bt full

How can I get a dump for backtracing? With drop_priv_before_exec=yes I get a config error: doveconf: Fatal: Error in configuration file /usr/dovecot/etc/dovecot/dovecot.conf: service(imap-login): drop_priv_before_exec=yes can't be used with chroot

You need to also set inside the service "chroot=" to disable chrooting. Also for imap-login to produce core files you need to set "executable = imap-login -D".
