SVM.PredictProbability crashes

[trenki2]

I wanted to use SVM.PredictProbability but unfortunately the method crashes:

This can reproduce the issue:

SVMProblem trainingSet = SVMProblemHelper.Load(@"problem.txt");

SVMParameter parameter = new SVMParameter();
parameter.Type = SVMType.C_SVC;
parameter.Kernel = SVMKernelType.RBF;
parameter.C = 1;
parameter.Gamma = 0.5;

SVMModel model = trainingSet.Train(parameter);

for (int i = 0; i < trainingSet.Length; i++)
{
	double[] estimations;
	var prob = SVM.PredictProbability(model, trainingSet.X[i], out estimations);
}

problem.txt

OK, it does not crash, when I set parameter.Probability = true but then I always get -1 for the probabilits.
