Filed upstream for comment.
This is fixed upstream: http://git.xfce.org/xfce/xfce4-settings/commit/?id=8d40a86ce47bff03704558061c5fbf0c65290e61 I can leave this open until we push an update with the fix, or we can close this and get it in the next update from upstream. Or do you think this is worth patching? I expect we will see a 4.8.2 soon, so it seems not worth it to me off hand.
