Bug description:
  [Impact]

  Unity might crash on systems with touch screen or multi-gesture
  supporting touchpads.

  [Test case]

  The crash is pretty random, it happens in some cases where unity is
  locked and after a suspension. Without having to touch any input.

  [Regression Potential]

  Regression potential: fix is very safe. We're just removing asserts in
  code, returning safe values and printing errors instead.

  
  Not sure if the cause is running autopilot tests.
