There is one redundant file in framework/po directory: fr.po.orig. I guess this is remain of bug in 0.3 version of Transifex (not used anymore, seems fixed in current 0.6) or just old mistake of committer. Should be removed. http://hg.fedorahosted.org/hg/setroubleshoot/file/1b8f40ff6dcf/framework/po/fr.po.orig#l1
Fixed in setroubleshoot-2.2.18
