Eye tracking calibration failing systematically for the same user

The eye tracking calibration seems to be constantly freezing in the middle for the same person.

Althought we're using 0.12.0 the problem seemed to be happening with 0.11.4. He does have the feeling the problem wasn't happening with 0.10.0.

Here's the log with 0.12.0:
