[Bug 57760] workspace schwicher fails to load configuration

[newen]

Public bug reported:

Binary package hint: gnome-applets

I removed and added the workspace switcher, and when I tried to change
the number of worspaces/rows I got the following error:

An error occurred while loading or saving configuration information for
gnome-panel. Some of your configuration settings may not work properly.

Failed: Failed: Schema `/schemas/apps/workspace_switcher_applet/prefs/display_all_workspaces' specified for `/apps/panel/applets/applet_7/prefs/display_all_workspaces' stores a non-schema value
Failed: Failed: Schema `/schemas/apps/workspace_switcher_applet/prefs/num_rows' specified for `/apps/panel/applets/applet_7/prefs/num_rows' stores a non-schema value

I tryed it with gconf but when I tried to modify something in /schemas/apps/workspace_switcher_applet it tells me that there is no schema and got the following error
Type mismatch: Expected `UNKNOWN, 5' got `Integer' for key /schemas/apps/workspace_switcher_applet/prefs/num_rows
