Extremely bad bug.

We're also failing "MW2: Active call stays active" because of this bug.
Guys, we need an owner of this. This bricks the device until rebooting.

Any idea what the regression that caused this is? Can we identify and backout asap?

Sure I will shelf other stuff and start looking into this now.
I was able to run though the MW0 case successfully with an eng otoro build from the 12-12 build. Going to try the mentioned build above to verify I can reproduce failure.
On the 12-11 build it seems possible to reproduce the issue. Upon investigating it seems like if the home screen is currently in the foreground then killed it cannot be restarted without rebooting the phone. Its fairly easy to reproduce this by: 1. Unlocking the phone 2. Page to first set of apps 3. get pid (adb shell b2g-ps) 4. kill homescreen while it is in the foreground (adb shell kill $PID)
