Restart error on add-on update

I am getting a log of an error in the command prompt. It appears after pressing the OK button to restart Orange for updating/installing add-ones via GUI. Although Orange restarts normally, someone should still look into it so it doesn't cause problems in the future.

The error:

--- Logging error ---

Thanks, @robertcv. We noticed that these restarts also cause some further errors. They seem connected with what you observe.
