dovecot - Feb 2014 - Segmentation fault

Hello,

I have encountered with strange issue. When I uncomment the following line

auth_verbose_passwords = yes

in the /etc/dovecot/conf.d/10-logging.conf I get the following errors

# dovecot -a
# 2.2.10: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-431.3.1.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4
# NOTE: Send doveconf -n output instead when asking for help.
Segmentation fault (core dumped)

# doveconf -n
# 2.2.10: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-431.3.1.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4
Segmentation fault (core dumped)

# dovecot -F -c /etc/dovecot/dovecot.conf
doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: (null)

All other options in the file works fine

# cat /etc/dovecot/conf.d/10-logging.conf | grep -v ^# | grep -v ^$
log_path = syslog
syslog_facility = mail
auth_verbose = yes
auth_debug = yes
auth_debug_passwords = yes
mail_debug = yes
verbose_ssl = yes

# uname -r
2.6.32-431.3.1.el6.x86_64

# cat /etc/redhat-release
CentOS release 6.5 (Final)

# dovecot --version
2.2.10

Any advice would be highly appreciated

gdb backtrace would be helpful:

gdb --args doveconf -n
run
bt full

I guess it's related to auth_verbose_passwords setting, but I can't
immediately see why it would crash there.
