Reading the comments it isn't clear the problem is on pulseaudio. In my case sometimes when I try to connect to my headset I get a crash on unity-control-center (not sure yet if it is related). After upgrading from Ubuntu 12.x I started to have this issue. I can pair my headset but when I try to connect it the system shows that the device is connected if you go on system tray menu and shows it is disconnected if you go through system settings -> bluetooth. But it don't work anyway.
