[Dovecot] Dovecot 1.2.5 segfaults.

[Tom Diehl]

Hi,

I just updated to dovecot 1.2.5 on centos5.

1.2.4 did not show this problem. I am going to roll back for the time being
but I am willing to do whatever I need to to fix this.

This is an x86_64 system. filesystem is ext3.

I am now seeing the following in the logs:
