Description of problem:
When running gnome-do-0.8.1.3-3.fc11.i586 the following error shows up a number of times:

Could not load desktop item: libgnome-desktop-2.so.7

Also when trying to enter Preference the application crashes - apparently due to the same problem with the .so file.

Marshaling button_release_event signal
Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
