Thanks for bringing this up. In an attempt to discover and fix more bugs,
we've added some error messages to functions which should never be passed
null--such as the ones you've listed here. Any time null is passed to one
of these functions, it means that the author of the code was not aware of
an object's existence, and it's likely that a bug will result.
There's an overall tracking task for this here (
https://phab.enlightenment.org/T7030) with subtasks being created for each
area that the errors are found in.
This is a good place for new contributors to jump in, as the fixes for
these issues just involve reading the code a bit to see why the passed
object does not exist.
