You have a corrupted cache file. Various things could have caused this, it isn´t easy to know what it was. Your fix works because once you rsync, there is no mention of the folder with the problem in the sync log any more, however next time anything happens on that folder you get the crash again. 1) figure out what folder it is 2) reconstruct it 3) profit???
