I have tested this and was unable to reproduce the error. I can remove the button from my form using the RemoveField function. Can you please provide the form that is causing the problem and the code that you are using to remove the button.
Thanks.

It appears that the form was created using Adobe LiveCycle Designer 8.0 which is currently not supported by the RemoveField function. Our developers are working hard on this issue and will have the solution in about two weeks time.
Thanks.
