AttributeError: 'NoneType' object has no attribute 'update_position'

That is the python error message when running podqast from terminal. The build is latest from tabsview branch.

There are two things that trigger it. Below are the two logs with errors, and a third with no problems.

The first is when an episode finishes on the playlist and it should advance to the next.

The second is when pressing play on the lock screen.

Both of these start to play nicely when I longpress an episode and then press play from the dropdown, as seen from the log below
