Problem running Polychart locally

[fccoelho]

Hi, I am trying to test Polychart but I am getting the following error in the gunicorn log:

Exception KeyError: Exception KeyError(140709551081280,)KeyError in : <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored
KeyError(140709551081280,) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored

Exception KeyError: KeyError(140709551081280,) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored

Any hints? I can't even load the web interface.

Byt the way, does Polychart listen by default on port 80? is there a way to change that?
