Steve, this seems to be a platform issue. My phone slows down as I start playing the radio; it rebooted even before I tried to kill the FM radio app. 

Can you take a look? Thanks.

Is it a dup of bug 800263?

It should be a dup. I am working on bug 800263. If bug 800263 is finised, I will check whether it solves this problem, too.

Hi nhirata,
Can you confirm this bug? After bug 800263 landed, I cannot re-produce it on my device.
Thanks.

Lawrence just tried reproducing this on an Unagi with 2012-11-14 and couldn't.  Please re-open if you can reproduce.
