    zeitgeist: fix use-after-free of a GPtrArray
    
    The Zeitgeist plugin creates a GPtrArray to give to libzeitgeist when
    registering a Zeitgeist datasource. libzeitgeist internally sinks this
    reference, but the plugin assumes the GPtrArray to still be available
    and later attempts to unref it.
