[Dovecot] 2.0.7 (a131a498731f): Core Dump on parsing Config

[Thomas Leuxner]

Trying to fix the 'lmtp' temp error, the latest HG core dumps right away:

Nov 30 04:15:41 spectre dovecot: master: Dovecot v2.0.7 (a131a498731f) starting up
Nov 30 04:15:41 spectre dovecot: master: Error: service(log): child 30087 killed with signal 11 (core dumped)
Nov 30 04:15:41 spectre dovecot: master: Error: service(log): command startup failed, throttling

Dump seems to be not very useful though.
