How to reproduce:
1. Create a new project WITH UNITY ANALYTICS ENABLED
2. Before Services window has finished loading, open 'About Unity' tab
-- Notice editor hiccups for a second and then all the credits disappear
-- If the editor doesn't hiccup, it doesn't reproduce

Expected behaviour: Names of all the employees and people who contributed to Unity
Actual: Two lines of text:
"Thanks to Forest 'Yoggy' Johnson, Graham McAllister, David Janik-Jones, Raimund Schumacher, Alan J. Dickins and Emil 'Humus' Persson"

Reproduced on: 2017.1.0b9, 2017.1.1f1, 2017.2.0a2, 2017.2.1p1, 2018.1.0b1
Not reproduced on: 5.6.1f1, 5.6.4p4, 2017.1.0a1, 2017.1.0b1, 2017.1.0b8, 2017.2.0a1

Note: Doesn't reproduce after reopening the project, but reproduces reliably using new project.

Fixed in: 2018.2.0a1
