Sakia first launch error

I've deleted my ~/.config/sakia folder and relaunched the software.

After choosing the option "Connect with an existing account", I fill in my secret identifiers, and click OK. I get the following error:

    Task exception was never retrieved
future: <Task finished coro=<ConnectionConfigController.process() done, defined at sakia/gui/dialogs/connection_cfg/controller.py:103> exception=TypeError('unorderable types: NoneType() > int()',)>
