Short description of error
Blender crashes when switching between scenes during a physics simulation. The 2nd scene was a full copy of the first.

Exact steps for others to reproduce the error

1. Open attached Physics.blend
2. Change scene to With Animation
3. Create a new Full Copy scene (should be named With Animation.001
4. Press Play Animation to start physics simulation.
5. While the animation is playing through the first time, switch back to With Animation scene.
6. While animation still playing through first time, switch to With Animation.001.

Notes
I noticed that if I let the physics simulation play 1 time through before switching scenes, the crash does not occur.
