Example sinkelement.py assertion failure: 'G_IS_OBJECT (object)' failed
gstreamer1 version: gstreamer1-1.16.2-2.fc32.x86_64
When running the sinkelemement.py example I am getting an assertion failure.

You need to explicitly set elements to the NULL state before dropping the final reference, to allow them to clean up. This problem may also be caused by a refcounting bug in the application or some element. sys:1: Warning: g_object_ref: assertion 'G_IS_OBJECT (object)' failed Caught SIGSEGV #0 0x00007fd5faae4b6f in poll () at /lib64/libc.so.6 #1 0x00007fd5fac2cace in g_main_context_iterate.constprop () #2 0x00007fd5fac2ce53 in g_main_loop_run () at /lib64/libglib-2.0.so.0 #3 0x00007fd5fada80c0 in gst_bus_poll () at /lib64/libgstreamer-1.0.so.0 #4 0x00005624f6bc0803 in event_loop () #5 0x00005624f6bbf64e in main () Spinning.
