Error: Managed Package Patch Modification Exception: A change was made to the patch release that will change the visible behavior of the application: Visualforce Component: xxForm: Cannot change attribute properties in a patch.

I have seen this before, it is a bug in the platform. If your sure you have not changed the 'access' attribute on your component or any of its attributes. Recommend you raise a support call, they sorted it for us.
