Laurens, I'm using v2.02, and am getting a strange behaviour on certain feeds. These are taking a long time to update, and then if I watch, they actually start counting backwards ... e.g. 79%, 78%, 77% ... until I stop them.
Could you see if you can reproduce my problems on ...
http://www.elsua.net/feed/
http://feeds.feedburner.com/ross (and
http://ross.typepad.com/blog/rss.xml )
http://feeds.feedburner.com/Torontoist
I have the setup for "Output only new feed items", if that makes a difference. Thanks.
