[Dovecot] Dovecot fails after updating MySQL

[Jerry]

I just updated MySQL to Server version: 5.5.8 on my FreeBSD-8.2 system.
Now Dovecot refuses to run. Prior to this, dovecot had been running for several
years without a problem.

This is the output of "dovecot -n"

The /var/run/dovecot directory looks like this:

This is the log file output, updated every second (snippet)

signal 11 (core not dumped)
Jan 10 18:42:11 dovecot: Error: child 34521 (auth-worker) killed with
signal 11 (core not dumped)

I have tried deleting and rebuilding dovecot without success. I am at a
lose to figure out what the problem is.
