I use the "Label for new torrents" with my RSS feeds to separate things for me and things for my wife. A couple of versions ago, this stopped working right, and I get a label containing 3 characters of gibberish (as an ex-programmer, I would say maybe it's a pointer rather than what's AT the pointer). I haven't found another report of this, and I figured it might be fixed in the next release, but there have now been two more releases with the same problem.
