Version: (using KDE KDE 3.5.7) Installed from: SuSE RPMs It is a bit of a bug too. Not excluding autostart limits usability of "save session" feature. Because after restart I have all apps from autostart and from previous session (so they are doubled).
Superseded by https://bugs.kde.org/show_bug.cgi?id=65511
Did I understand it correctly that bug 65511 belongs to konqeror pages and this one belongs to KDE sessions and autostart applications? If so this one still happens in KDE 5.
