Segmentation Fault when Passing Color Image to detect

[cancan101]

eg, running this on a color image:

import cv2
from pupil_detectors import Detector2D
detector = Detector2D()
detector.detect(cv2.cvtColor(cv2.imread('/Users/me/Downloads/iris.png', cv2.IMREAD_COLOR), cv2.COLOR_BGR2RGB))

Causes a segmentation fault.
