>Description:
	The zfs-snapshot tool is called from crontab every five minutes:
        */5 * * * *   root   /usr/local/bin/zfs-snapshot-mgmt
        Every call causes the error message:
        /usr/local/bin/zfs-snapshot-mgmt:130:in `join': can't convert nil into String (TypeError)
	from /usr/local/bin/zfs-snapshot-mgmt:130:in `snapshots'
	from /usr/local/bin/zfs-snapshot-mgmt:137:in `snapshots_to_remove'
	from /usr/local/bin/zfs-snapshot-mgmt:145:in `remove_snapshots'
	from /usr/local/bin/zfs-snapshot-mgmt:213:in `block in <main>'
	from /usr/local/bin/zfs-snapshot-mgmt:210:in `each'
	from /usr/local/bin/zfs-snapshot-mgmt:210:in `<main>'

>How-To-Repeat:
	Just install on FreeBSD 10-stable or release and wait till it is called from crontab or execute it manually with:
        /usr/local/bin/zfs-snapshot-mgmt
