Automatic Animation Compression Results in Crash

Using the "Automatic" option to compress animation results in crash 100% in UE4.10 but does not occur in UE4.9.2. *Regression

1. In UE4.10, Open new Third Person Project
2. Open any animation in Persona
3. Select Compress animation from menu, using "Automatic" option
RESULT: Crashes 4/4
EXPECTATION: Animation to compress without crash
NOTE: This does not occur in UE4.9.2
