konqueror included in kdebase 2.1-6 is badly broken, the toolbar is duplicated and in WWW browser mode the "Arioso" font is used as default, ignoring font settings in control center and Konqueror settings. In file browser mode only the icons are visible on right pane, no filenames or other data.
No, the update path is badly broken. We've tried to replace a directory (/usr/share/config) with a symlink, which rpm can't handle well. I've reverted the change, but you'll need to uninstall and reinstall the KDE packages to get rid of the damage.
