mixGaussFit(data, nmix, varargin) with 'nrandomRestarts',100

What steps will reproduce the problem?
1. x = some_test_data 
2. mixModel = mixGaussFit(x, 2,  'verbose', true, 'maxIter', 
100,'nrandomRestarts',100);

What is the expected output? What do you see instead?
********** Random Restart 2 **********
initializing model for EM
??? Undefined function or variable 'd'.

system?
PMTK (r2774)/Windows (Matlab)

Please provide any additional information below.
Failure in 
function model = initGauss(model, X, restartNum, initParams, prior)
when restartNum ~= 1
mu              = randn(d, nmix);
regularizer     = 2; 
Sigma           = stackedRandpd(d, nmix, regularizer); 
model.mixWeight = normalize(rand(1, nmix) + regularizer); 

We need to define d from model or from data.
