No RDBMS driver specified

[gionn]

Freshly installed roundcube on a Debian Squeeze from binary packages (0.7.1-1~bpo60+1)

Getting while accessing vacation preference tab:

[05-Sep-2012 22:49:49] MDB2 Error: not found (-4): no RDBMS driver specified
[05-Sep-2012 22:49:49 +0200]: DB Error: no RDBMS driver specified in /usr/share/roundcube/program/include/rcube_mdb2.php on line 104 (GET /?_task=settings&_action=plugin.vacation)

Relevant configuration:

/*
 * SQL driver
 */
include_once("/etc/roundcube/debian-db.php");
// database DSN
$rcmail_config['vacation_sql_dsn'] =
        "$dbtype://$dbuser:$dbpass@$dbserver/$dbname";

Any hint?
