It would appear that e16 and e17 ignore or otherwise do not implement various portions of the the specs that AllTray depends on. I have filed a bug with the Enlightenment people[0] to request that these be implemented. I don't know that e16 will ever get fixed (AllTray's breakage is only minor there), but hopefully they'll fix e17 so that AllTray can properly run on it.
