Just noticed a few lines up in the sync.log that there is a file with a <DF> in the name (highlighted, when I view sync.log with less). When I view sync.log with emacs it's this character: ß and when I look at the actual file on the original machine (a linux box), it has a question mark in the name. I'm not sure where that came from, but could that be the problem? It does not exist on the Mac, like it never actually go copied over. Wow! Getting off topic now, but I had synced the same folder using Spideroak before, and I just looked at the destination folder and that file with the ? in the name is completely missing. Spideroak just silently skipped right over it, apparently. I guess other apps have problems with that filename too...
