           Summary: StartActivity() requiring intent to have
                    FLAG_ACTIVITY_NEW_TASK and not assuming the caller's
                    task affinity

So, according to Android docs, if we startactivity from another activity, by
default, the task affinity of the new activity should be to belong to the same
Task that the calling activity belongs to.
http://developer.android.com/guide/topics/fundamentals.html#afftask

However, I'm noticing that I get an error:
android.util.AndroidRuntimeException: Calling startActivity() from outside of
an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really
what you want?
at android.app.ApplicationContext.startActivity()

Check out the code I'm using in the Additional Notes.  But, I'm passing 'this'
as the context where this is an Activity, however the stacktrace is showing
that ApplicationContext seems to be what's used.  Perhaps this is the problem? 
The context needs to be the Activity's context?

I know if I add the ActivityFlags.NewTask (FLAG_ACTIVITY_NEW_TASK) it works,
but I believe the point is, I should not have to do that.

Reproducible: Always
