DeepStream SDK 4.0 on Nano : warning fresh after install

On the Nano, immediately after installation of DS 4.0,
I do a delete of the gstreamer cache followed by


I get

(gst-plugin-scanner:23574): GLib-GObject-WARNING **: 15:03:52.020: cannot register existing type ‘GstInterpolationMethod’

(gst-plugin-scanner:23574): GLib-GObject-CRITICAL **: 15:03:52.020: g_param_spec_enum: assertion ‘G_TYPE_IS_ENUM (enum_type)’ failed

(gst-plugin-scanner:23574): GLib-GObject-CRITICAL **: 15:03:52.020: validate_pspec_to_install: assertion ‘G_IS_PARAM_SPEC (pspec)’ failed

This is followed by normal output.

The print is harmless and not triggered by Deepstream SDK 4.0. Since we are integrating NVIDIA plugins with 3rdparty gstreamer 1.14.1, there could be some warning messages reported by 3rdparty code. It is harmless and please ignore it.
