After installing kdebase-3.0.4-1 I went to the settings option of konqueror and clicked on the "Netscape Plugins" icon, at which point I got the error message saying that it could not find nsplugins.desktop. I made a copy of kde-nsplugins.desktop to nsplugins.desktop and restarted KDE, this solved the problem. So, I guess we have some kind of a desktop file issue. PS: Thanks for resolving the konsole scroll, screensaver, and flash bugs.
i confirm this issue. It's fixed in kdebase-3.0.4-2 or newer. Please make sure that kdelibs-3.0.4-1 or new has been installed.
