Such errors sometimes occur when the user removes entries from the download history using the web interface. Also, they sometimes occur between downloading and post-processing. There must be a mistake in `backend.hubs.general.DownloadListUpdater.apply_slots'.

The bug has not entirely been fixed yet. It sometimes still occurs when a download is being completed.
