- This configuration widget exists from the first show() until the end of the applet. Consequently, it got notified about all feeds loaded and kept adding them to the list widget in the configuration dialog. This bug was reported in Bug 157948.

The primary fix is to not stay connected to the NewsFeedManager all the time but only while we're adding a feed. We do an aditional check for the URL which was loaded, just in case a feed update of some other URL finishes while we're retrieving the to-be-added feed.
