ZodbConnection.close_zodb(s)


Its basically a class file.I have tried debugging and have foudn outthat
removing this line of code result s in no error.

if not root.has_key("Players"):
    root['Players'] = {}
PlayerRoot=root["Players"]


But i have the same lines of code in another class file in the same
module.So i cant understnd why this error occurs.Any help would be much
appreciated.

Thanks,
Rohit.
