in version 2.2.x the standard database format changed from berkeley
to skiplist.
you have two options now:
stay with the berkeley format -> put into your /etc/imapd.conf file
the statement
seenstate_db:  berkeley

or convert your relevant databases from berkeley to skiplist format
by using cvt_cyrusdb (type the command for usage)

This little scrip helped me:
assuming your imap databases in /var/imap:
(run as user cyrus)
--------------------
CFGDIR="/var/imap"
DBNAMES="`find $CFGDIR/user -name '*.seen'`"
for DB in ${DBNAMES}; do
        cp -p ${DB} ${DB}.berkeley
        cvt_cyrusdb ${DB}.berkeley berkeley ${DB}.skiplist skiplist
        cp ${DB}.skiplist ${DB}
done
---------------------
