I've just asked abrt maintainer.

This message is misleading, because "res:1" means duplicate, so it's not bad nor corrupted 
crash, but coredump should be already stored in different directory.

How can you find it? Try:

grep -r dovecot /var/spool/abrt/*/component

it'll tell you what directory contains dovecot's crash. For example:

/var/spool/abrt/ccpp-1302856889-1869/compoment:dovecot

so core file would be: /var/spool/abrt/ccpp-1302856889-1869/coredump


Before gdb,you need to install debug info symbols:

debuginfo-install dovecot

and then, you can use:

gdb /usr/libexec/dovecot/imap /var/spool/abrt/ccpp-1302856889-1869/coredump
