My "administrative" user experienced the same symptoms after upgrading the 80 packages that were updated since Apr 11. Invoking the "Windows" Preferences gave a popup "Cannot start the preferences application for your window manager", "Window manager "unknown" has not registered a configuration tool. Removing the ~/.gnome2 directory made the symptoms disappear. Root did not experience the problem.
