miui 1.10.14 on hd2: ring tone only rings one time

Oct 2, 2011
Re-installed the version 1.10.21 by scratch with task29 etc. (clean install). After the install a selected ring tone is correctly repeated till the call is on going. As soon as I register with Google account on the market and it start ringing only one time. This is the only operation done after a clean install!! I tried different time.

PS: Please how to communicate bug to the development team so that they can be visible to them??
