gnome-panel crashed with SIGSEGV in g_closure_invoke()

Binary package hint: gnome-panel

I added the Network Monitor applet to the panel, it crashed, and a message popped up and told me that the Deskbar applet was not performing correctly, and asked if I would like to delete it. I clicked delete. The Network Monitor applet is still there. It removed all of my launchers. Sorry if that is a little vague, more information should be attached.
