NetMQ problem when calibration starts

[joobei]

When I press 'c' to begin calibration there is an exception error.

TerminatingException: CheckContextTerminated - yes, is terminated.
NetMQ.Core.SocketBase.CheckContextTerminated ()
NetMQ.Core.SocketBase.TrySend (NetMQ.Msg& msg, TimeSpan timeout, Boolean more)

PupilGazeTracker.StartCalibration () (at Assets/Scripts/PupilGazeTracker.cs:2096)
PupilGazeTracker.Update () (at Assets/Scripts/PupilGazeTracker.cs:880)

This is the offending line:

hmd-eyes/unity_pupil_plugin/Assets/Scripts/PupilGazeTracker.cs

Line 2096 in 6590328

_sendRequestMessage ( new Dictionary<string,object> {{"subject","start_plugin"},{"name",_currCalibModeDetails.calibPlugin}});

I believe this code is long replaced.
