There are many redundant files in po directory, which names ends with '.orig' and '.rej'. I guess these are remains of bug in 0.3 version of Transifex (not used anymore, seems fixed in current 0.6) or just old mistakes of committers. Should be removed. http://git.fedorahosted.org/git/?p=system-config-services.git;a=tree;f=po;hb=HEAD
fixed in git
