For two above messages and my own findings is that it *looks* like that hildon-desktop (i have community ssu and MAG's hildon-desktop that comes with it) crashes. I havent had time to debug into this but my setup is as follows: main desktop has media player widget and calendar widget and if i try to enable drlauncher, hildon-desktop will crash, drlauncher wont appear and rest of the widgets won't get re-loaded either ..
