--- Comment #51 from Adam Williamson awilliam@redhat.com --- So #860276 gives us a very solid basis to accept this as a blocker: it breaks firstboot. I confirmed this myself. 'LC_ALL=es.UTF-8 firstboot' crashes, firstboot does not run at all. 'LC_ALL=es_ES.UTF-8 firstboot' runs fine. Other languages are affected, at least Japanese. So this bug causes firstboot to fail to run in several languages, breaking the Alpha criterion "In most cases (see Blocker_Bug_FAQ), a system installed according to any of the above criteria (or the appropriate Beta or Final criteria, when applying this criterion to those releases) must boot to the 'firstboot' utility on the first boot after installation, without unintended user intervention, unless the user explicitly chooses to boot in non-graphical mode. This includes correctly accessing any encrypted partitions when the correct passphrase is supplied. The firstboot utility must be able to create a working user account".
