Crash in MatineeCameraShake when scrubbing and saving

[Link Removed]

1. In Fury
2. In the viewport, turn on Allow Camera Shakes
3. Open Neymar_P and Neymar_Master 
4. Scrub around the first two shots, mainly the second shot
5. Save current level
6. Scrub around the second shot
7. Open levels browser and set Neymar_Art current and save
8. Scrub around the second shot
9. Open levels browser and set Neymar_Landscape current and save
10. Scrub around the second shot
11. REPEAT

The crash is pretty consistent, but there's not exact consistent steps to repro that I could figure out. But it crashed within roughly 30 seconds of doing the above.
