ClientApiException - JsonParseException: First element must be "log"

Hi,
the following exception messes up with my tests, and I haven't been able to figure out the cause yet.
Does anybody have any ideas? I'm really stuck in this one ...
For the record, I'm testing web services using the authorization story, and the error occurs in method getProxy().makeRequest(...) .
