trollhare's dashboard

I accidentally added a feed I'm not interested in by some feature that was collecting sites I visit - and I can't unsubscribe.The feed is

feed/http://www.svd.se/?service=rss&type=senastenytt

Unlike some other report, I DON'T have problems with firefox crashing. The only thing that happens is that when I tick the "unsubscribe" button nothing happens. I can unsubscribe to other feeds, but not this particular one. Maybe it doesn't sound that bad, but since the feed posts new items several times per hour it's starting to annoy me.
