"NullReferenceException: Object reference not set to an instance of an object" when exiting Play on OSX only.

Happening only on OSX, both OpenGL 4.1 and Metal.

1. Open attached project (there should only be a single script file inside)
2. Window -> ProgressbarTest (this will open a new window)
3. Enter and exit Play mode a few times

Expected: No errors in console
Observed: NullReferenceException: Object reference not set to an instance of an object

Occurring on: 2017.1.0b1 onwards
Not occurring: 2017.1.0a6 and older, 5.6.0f3s2, 5.5.3f1
