Dropbox - TypeError: 'NoneType' object is not callable

Can't start backup while Dropbox as a remote location is enabled, because an exception is thrown:

Usually one of two things is happening with this type of error.

1. You haven't authorized the Dropbox service, so no token file exists. Take a look at the instructions if you think this is the issue.
2. The file is missing or corrupt for some other reason. Try deleting the tokens.json file and re-authorizing.

Hi.

I have the exact same issue. I created a dropbox app. Used api key in XbmcBackup, authorized (a message confirmed it was authorized). Then I try to backup and I have the same error. I then removed tokens.json, set the api key/secret and re-authorized but it didn't work better.
