I know that I has just released 0.1.1 only 5 days ago but it worths to upgrade if it has a good enhancement like this.
According to a problem connecting to some private trackers posted at http://www.howforge.com/cant-connect-to-most-private-trackers#comment-126, I managed to solve this problem by just ignoring extra characters in data sent from those trackers. Thanks to dodgy to help me find out this problem.
Just that! Only minor enhancement but it worths to upgrade because it works properly with all trackers.
