[Dovecot] Segfault with soft disk quota

[Tim Boyer]

RHEL 5.1, dovecot 1.0.rc15 on a x86 system.  dovecot -n says

[root at dg mail]# dovecot -n
# /etc/dovecot.conf
protocols: pop3 pop3s
login_dir: /var/run/dovecot/login
login_executable: /usr/libexec/dovecot/pop3-login
login_process_size: 64
first_valid_uid: 100
mail_executable: /usr/libexec/dovecot/pop3
mail_plugin_dir: /usr/lib64/dovecot/pop3
auth default:
  passdb:
    driver: pam
  userdb:
    driver: passwd

I had one user whose Outlook kept giving disconnection problems.  I looked
at the logs, and found this:

Mar 31 14:05:31 dg.denmantire.com dovecot: POP3(bfarner):
open(/home/bfarner/Mail/.imap/INBOX/.temp.dg.denmantire.com.4668.564b08eac94

signal 11

Strange thing is - he's over disk quota, but just over the soft quota -
nowhere close to the hard quota.

Easy for me to fix, but I figured I'd also submit it as a bug.  I don't
follow the list so if you need any more info, please copy my email on the
reply.  Thanks...
