While Editing a Widget Blueprint the editor will crash under following reproducable circumstances:  
Fresh FPS Blueprint Project

1. Create WidgetBlueprint
2. Create Button
3. Add 2 Animation
4. Create a new animation track for the button (for example opacity) in one of the animations
5. Switch to display curves for animation editing
6. You click on the other animation.
7. It crashes.
