Short description of error

If you separate part of a mesh to make a new object, any f-curves in the orginal object are shared by the newly separated object. These cannot be independently edited. They seem to share a single instance.

Exact steps for others to reproduce the error

Start with a mesh (default cube for example)
Animate it.
Edit it, select some part of it and use Separate by selected.
Select the new object
Go to F-curves.
You should see copies of the curves from the orginal object's animation.
Delete the F curves.
Go back to orginal object and run animation
ERROR - there is no animation.

The data appears to be a single instance shared by the two objects. Editing one means editing both.

To get around this...
Go back to the point where you have separated and selected the new object
- Duplicate the separated object
Delete the first separated object but keep its duplicate
Go to f-curves and delete them for the dulicated object
(Now the data can be edited for the duplicate and is independent of the original object.)
Run animation

the cube is animated.

This isnt a bug, You can make animation data single user:
go to Object -> Make Single User -> Object Animation

The same goes for duplicates. (made with Alt+D duplication)
