imap coredump after doveadm altmove

[Frank Koch]

Hello,

i tried to move mails to an alt storage with the following command:

doveadm altmove -u user at domain.de mailbox Inbox

After that, the imap process produces a core dump (files has not been 
moved):

Maillog:
dovecot: imap-login: Login: user=<user at domain.de>, method=PLAIN, 
rip=X.X.X.X, lip=X.X.X.X, mpid=5393, TLS, session=<83JiHqNdTwCsEAIf>
dovecot: imap(user at domain.de): Fatal: master: service(imap): child 5393 
killed with signal 11 (core dumped)

Version: Dovecot 2.2.18.2
OS: CenotOS6 2.6.32-696.10.2.el6.x86_64
local storage (ext4)

#gdb --args /usr/libexec/dovecot/imap -u user at domain.de
