dovecot - Feb 2014 - Fatal: master: service(pop3): child 20972 killed with signal 11

Hello,

since V 2.2.11 I get that error with pop3.
With imap everything is fine.

Feb 12 13:06:40 server2 dovecot: pop3-login: Login: user=<user>, 
method=PLAIN, rip=84.183.42.55, lip=195.137.213.14, mpid=20972, TLS, 
TLSv1 with cipher AES128-SHA (128/128 bits)
Feb 12 13:06:41 server2 dovecot: pop3(user): Fatal: master: 
service(pop3): child 20972 killed with signal 11 (core dumps disabled)

Upgrade/Bugfix is coming?
