After poking around in the current deluge.py I found a lovely comment:

# deluge client lib chokes on future's newlist, make sure we have a native python list here

changing

self.get_torrents_status(list(self.settings_map.keys()) + config.get('keys', []))

to

self.get_torrents_status(native(list(self.settings_map.keys())) + config.get('keys', []))

and adding

from future.utils import native

in deluge.py resolves this issue.

@gazpachoking Please add these changes to #2102
