There are two 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-date.git;a=tree;f=po;hb=HEAD
In addition to po/de.po.rej and po/ta.po.orig, also po/timezones/fr.po.orig and po/timezones/sk.po.orig need to be deleted.
fixed in git
