fi_backup fails when local LANG is fr_FR.UTF-8

[MaxiReglisse]

Very good job, Davide ! thanks.

but when LANG is set to fr_FR.UTF-8, fi_backup fails because the VM is not seen as running, as you can see here :

# LANG=fr_FR.UTF-8 && ./fi-backup.sh -c -b /var/lib/libvirt/backups/generic -d generic
[INF] libVirt version '1.3.1' support is experimental
[DEB] /usr/bin/qemu-img version '2.5.0' is supported
[DEB] QEMU/KVM version '2.5.0' is supported
[DEB] Domains NOTRUNNING to backup:  generic
[DEB] Domains RUNNING to backup: 
[ERR] Consolidation only works with running domains. 'generic' is not running! Doing full backup only of 'generic'
[ERR] Skipping consolidation/backup of 'generic'

the problem comes from the result of the virsh command. it answers "en cours d'exécution" instead of "running".

# LANG=fr_FR.UTF-8 && virsh -q domstate generic
en cours d'exécution

# LANG=en_US.UTF-8 && virsh -q domstate generic
running

Consequently, i need to prefix the fi_backup command with LANG=en_US.UTF-8

# LANG=en_US.UTF-8 && ./fi-backup.sh -c -b /var/lib/libvirt/backups/generic -d generic

what do you think ?
is it possible to fix the code perennially ?
Thanks in advance.
