cubicweb #1368805 i18ncubicweb command does not display error msg from xgettext. exit code -1 is not very helpful [open]

I think this could be improved by modifying the "call(cmd, shell=True)' statement in i18n.py, line 67. Maybe it suffices to delete 'shell=True'. Or are there any side effects of this suggesting another way to see the messages?
