I had the same problem while i installed xpenguins applet with synaptic on edgy then when i added the applet to the panel, gnome panel freezed and became unusable restarting gdm and restarting the computer did not solve the problem and at last i fixed it by uninstalling the xpenguins applet using synaptic.
