The suffix is included twice when CONFIG_mysql_dump_latest= is enabled and compression is used:
cp: cannot stat '/var/backup/db/fullschema/fullschema_daily_2015-06-04_17h38m_Thursday.sql.gz.gz.enc': No such file or directory

cp: cannot stat '/var/backup/db/daily/alvin/daily_alvin_2015-06-04_17h38m_Thursday.sql.gz.gz.enc': No such file or directory
It's a simple fix though on line 307:
root@db1:/usr/local/bin# diff automysqlbackup automysqlbackup.orig
307c307
< cp -al "${1}.enc" "${CONFIG_backup_dir}"/latest/
cp -al "${1}${suffix}.enc" "${CONFIG_backup_dir}"/latest/2255c2255
