File /etc/dovecot/conf.d/01-mail-stack-delivery.conf comes from special package that sets both postfix and dovecot. Knowing that deliver doesn't support include, postifx in Lucid is explicitly set as:
mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/conf.d/01-dovecot-postfix.conf -n -m "${EXTENSION}"
In Natty, that's:
mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/conf.d/01-mail-stack-delivery.conf -n -m "${EXTENSION}"
So, I'm not sure how would 'include' or 'include_try' create any problem?
Can you check your mailbox_command in /etc/postfix/main.cf?
