Array Causes ListModel Errors

I have a ListModel called myListModel and the code

var array1 = [1, 2, 3];
myListModel.setProperty(row, "values", array1);

causes the error message

<Unknown File>: Can't create role for unsupported data type

for a valid value of row while the code

var array2 = [0, 0, 0];
myListModel.append(

);

causes a popup window to appear stating that my project's ".exe has stopped working."

QTBUG-33564 is a related bug for dates.
