--galera-info fails in 2.1.1

Yesterday, I upgrades to xtrabackup version 2.1.1, and now my backups fail.

The commandline is
/usr/bin/innobackupex --user=... --password=... --slave-info --galera-info --stream=tar /srv/backup/xtrabackup/

and this results in

xtrabackup_55 version 2.1.1 for Percona Server 5.5.16 Linux (x86_64) (revision id: 600)

And this never completes.
