Unity 4.5.2 bug changing the properties of the 2d colliders in animation

hello, i was using unity 4.5.1 when I created an animation where I changed the propierties of circlecollider2D and boxcollider2D it worked perfect. When i updated to unity 4.5.2 those animations don’t update the values ​​they have in the animation and always stay by default.

Am I the only one who have this problem?

Well, this bug has been fixed in the new version 4.5.3
