There is no "bump" here.

Typically, you get such errors when disposing (freeing) your pipeline
when it's not in NULL state yet, just as the error says - ie., you need
to give GStreamer a chance to go through the state-changes to reach NULL
before disposing your pipeline and its elements.

One way to do that is to use (the Python equivalent of) a blocking
gst_element_get_state after you set the state.

Cheers,
Dirk.
