It would be useful to get gdb backtrace from this. You should be able to get core dumps by adding to dovecot.conf:

service auth {
  user = root
}

Run "ulimit -c unlimited" before starting dovecot. Then when it crashes there should be a core file in your base_dir (e.g. /var/run/dovecot), and you can do:

gdb /usr/local/libexec/dovecot/auth /var/run/dovecot/core

The newer hg versions generally should be more stable, since I've mainly been trying to fix bugs instead of add new features.. The exception being this week, since I've needed to do a few bigger changes.
