drush archive-dump @sites - wrong manifest

When I export my multisite installation Drush created manifest.ini file where is mistake in database dump file name. This costs wrong file is used while restore. Both dump files are included to the archive correctly.

[Global]
datestamp = "1344615598"

generator = "Drush archive-dump"
generatorversion = "5.4"

files-public = "sites/default/files"
database-default-file = ".www.sagar.web#osbeskyd.cz-sagar_osbeskydcz.sql"
database-default-driver = "mysql"
