Calibration function EyeTribe error after two calibration attempts

[hannehuygelier]

When I use the tracker.calibrate() function it runs correctly for the first two calibration attempts, but if calibration has still failed after these two first attempts and you ask to restart the calibration, the following error comes up:

tracker.calibrate() File "C:\Python27\lib\site-packages\pygaze_eyetracker\libeyetribe.py", line 195, in calibrate self.eyetribe.calibration.start(pointcount=len(calibpoints)) File "C:\Python27\lib\site-packages\pygaze_eyetracker\pytribe.py", line 1128, in start {'pointcount':pointcount}) File "C:\Python27\lib\site-packages\pygaze_eyetracker\pytribe.py", line 391, in request success = self.get_response() File "C:\Python27\lib\site-packages\pygaze_eyetracker\pytribe.py", line 435, in get_response self.resplist.append(self.parse_json(r)) File "C:\Python27\lib\site-packages\pygaze_eyetracker\pytribe.py", line 545, in parse_json parsed = json.loads(jsonmsg) File "C:\Python27\lib\jsoninit.py", line 338, in loads return _default_decoder.decode(s) File "C:\Python27\lib\json\decoder.py", line 365, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "C:\Python27\lib\json\decoder.py", line 381, in raw_decode obj, end = self.scan_once(s, idx) ValueError: Expecting object: line 1 column 311 (char 310)

Should be solved with this commit.
