Title:
  Zeitgeist plugin read/write after free on datasource registration

Status in gedit:
  Unknown
Status in gedit package in Ubuntu:
  Triaged

Bug description:
  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.

  The attached patch adds a reference to the GPtrArray to keep it
  available until the end of the plugin's initialisation code, where it
  is unrefed. The patch is designed to integrate with quilt on top of
  gedit 3.10.4-0ubuntu10.
