[Dovecot] 2.0.2 : crashes with LDA

[Jakob Curdes]

> Strange, because it is doveconf that is crashing. You mean doveconf -c /etc/dovecot2.conf doesn't crash?
No, it parses the config without errrors as far as I can see (below).
It seems only to crash when called in the contect of the LDA - perhaps a 
permission problem that is not handled properly?
On the other side, all config files and the conf.d directory are 
readable by everyone, just checked that.
