Dovecot IMAP stops working after CentOS 5.2 upgrade

This is mostly an FYI, but after performing the CentOS 5.2 upgrade, I had to re-run this command in order to make IMAP work again:

chmod 777 /var/lib/dovecot /var/lib/dovecot/index /var/lib/dovecot/control

I posted this on the forums as well, but I wanted to let you know that thus far that is the only thing that broke in the upgrade.
