Just noticed, whilst trying to reproduce kinggo's report:

Swipe from an open app to the events view, then swipe back. You are not back in the app you came from, you are in the home screen. Very annoying.

At least I think it is new. I have a vague recollection of something like that in very early releases but I thought it was fixed a long time ago. It would annoy me beyond words otherwise. Or was it a patch that no longer works?
