It seems that it suffices that decodebin is in the PAUSE state to have
that leak. For example:

#include <gst/gst.h>

main (int argc, char *argv[])
  GstElement *pipeline;
  GstElement *filesrc;
  GstElement *decodebin;

  gst_init (&argc, &argv);

  pipeline = gst_pipeline_new ("pipeline");

  filesrc = gst_element_factory_make ("filesrc", "filesrc");
  g_assert (filesrc);
  g_object_set (G_OBJECT (filesrc), "location", argv[1], NULL);

  decodebin = gst_element_factory_make ("decodebin", "decodebin");
  g_assert (decodebin);

  gst_bin_add_many (GST_BIN (pipeline), filesrc, decodebin, NULL);
  gst_element_link (filesrc, decodebin);

  gst_element_set_state (pipeline, GST_STATE_PAUSED);

  gst_element_set_state (pipeline, GST_STATE_NULL);
  gst_object_unref (pipeline);

  gst_deinit ();

  return 1;
