Tim-Philipp Müller 8ea948df92 gst/gstminiobject.c: Fix lcopy for mini objects, the mini object needs to be ref'ed.
Original commit message from CVS:
* gst/gstminiobject.c: (gst_value_mini_object_lcopy):
Fix lcopy for mini objects, the mini object needs to be ref'ed.
* tests/check/gst/gstminiobject.c: (my_foo_init),
(my_foo_get_property), (my_foo_set_property), (my_foo_class_init),
(test_value_collection), (gst_mini_object_suite):
Add test to ensure refcounts end up as expected when passing
GstMiniObjects through g_object_get() and g_object_set().
