Gnome-2.6.2 mixer applet panel problem after 06/15/2004 updates

[supraexpress at globaleyes.net]

After update Gnome-2.6(.1) components to 2.6.2, the mixer applet is no longer
available:

The panel encountered a problem while loading "OAFIID:GNOME_MixerApplet".
Details: Failed to resolve, or extend
'!prefs_key=/apps/panel/profiles/default/applets/applet_4/prefs;
background=none:;orient=up;size=x-small;locked_down=false

Do you want to delete the applet from your configuration?
