I have also must report a 'bug'. I dont know if it is PA or something else, but Google Camera doesnt work for me. It always crashes after I took a picture or even if I could make a Panorama pic it would crashes during the rendering process. Its quite annoying, since I use the camera very often. I now switched back to CM, till this 'bug' is fixed though.
