Afternoon all.
I'm seeing a segfault in dovecot 2.2.12 (debian package 1:2.2.12-2). I
can log into dovecot fine with mutt, but the segfaults seem to occur
when postfix (2.11.0, debian package 2.11.0-1+b1) tries to deliver a
message.
This was working fine under 2.2.9 (I can downgrade to that and delivery works).
Can anyone help? Doveconf -n, and backtrace follow.
