Version: (using KDE KDE 3.4.1) Installed from: Gentoo Packages There is a bug in the context menu "Mark Article". If you mark an already readed article as unread and then as new, the feed counter will be increased two times, while only one article is unread and you can increase it maybe endless by repeating that. If you mark then the article as read by clicking on it, the counter will be decreased only by one, multiple clicks on the article does not decrease the counter. After restarting akregator, the counter will show the real number of unread articles.
This has already been fixed in SVN, however it did not make its way into 3.4.1.
Hm, sorry, don't know why I changed the platform. :-(
