Comment:

 Re-opening as I can reproduce the less-useful-exception in 2.2.1 vs 2.2
 (via Python 3.6)

 The correct error which should be surfaced is (2.1):
 {{{
 NameError: name 'a' is not defined
 }}}

 The error which is surfaced currently (2.2.1) is:
 {{{
 django.core.exceptions.ImproperlyConfigured: The included URLconf
 't30500.urls' does not appear to have any patterns in it. If you see valid
 patterns in the file then the issue is probably caused by a circular
 import.
 }}}

 Example reproducible project is available: https://github.com/kezabelle
 /django-bug-30500
 Steps to reproduce:
 - runserver the project under 2.1
 - Uncomment the "a" in "t30500/views.py" to trigger the reloader and the
 exception to stdout

 Do the same under 2.2, and the error won't turn up.
