dovecot - Feb 2009 - Dovecot 1.2.beta1 Backtrace POP3

I am testing out the new Dovecot 1.2.beta1 software. I am getting
reports from people using POP3 that it randomly drops connections.
Looking at the log file I see that the POP3 process they were connecting
to panics and dumps a Raw bactrace. Below is a copy of the logs (IP
addresses striped for security):
