Force close when change Notification ringtone to None

[LifeBook]

Hi,

HTC Desire, MIUI latest beta version 1.10.28

I have tried to change the Notification ringtone to None but it does not work. And display the force close popup.

However, the notification ringtone works fine on 1.10.21

Thanks.

I have the exact same problem. Tried to reflash but same thing happens.

EDIT: I´m on Galaxy S if that matters
