To get rid of a plug, you must gtk_object_destroy it. If you
gtk_object_unref it, without gtk_object_ref'ing it first you are doing
something illegal -- you are doing an unref of a reference you don't hold.
Since the object holds a reference to itself, no amount of gtk_object_unref
will make it go away.

If you call gtk_object_destroy and someone else has done a gtk_object_ref,
the object will be destroyed, but not finalized, until the code that did the
ref does a gtk_object_unref. When it does, the object will be finalized. The
reference that the object held on itself because it's a top level container
is gone (went away at destroy time).

Patch looks good to me.
