To reproduce:
1. Open attached project ("UnityBursts")
2. Add a Script Component to a default Camera
- Errors are continuously thrown in the Console
3. Close Job Inspector window
- Unity freezes and crashes

Reproduced with(crash): 2018.3.11f1, 2019.1.0b9
Reproduced with(errors): 2019.2.0a10
Issue does not reproduce if any previous to 1.0.0 preview 6 Burst package is used

Notes:
- Can not be tested with 2017.4 as ECS and Burst were implemented in later releases
- ECS package version does not influence the outcome
