Original commit message from CVS: * gst/arg-types.py: Caps used as arguments of virtual methods should keep their initial refcount when calling the python methods. This is similar to the patch done for GstMiniObjects. * gst/gstbase.override: Adjust the gst.BaseTransform.get_unit_size() virtual method for above fix.
