Changes between Initial Version and Version 1 of Ticket #18850, comment 3

initial	v1
1	1	Yes, i know that with reordering the app in `INSTALLED_APPS`, the problem can be solved, but why django silences the import errors? can say django, don't do that, and raise import errors?
	2	and in this specific case why `X` is `None` and at least isn't undefined.
