23761	Mysql validator crashes with None db_type return. - Backport of master fix to 1.7	Adam DePue	nobody	"A fix was made in August in master:
https://github.com/django/django/commit/e9103402c0fa873aea58a6a11dba510cd308cb84#diff-14

The fix contains a lot more than is needed for this specific issue, however the specific changes to django/db/backends/mysql/validation.py would be great to have in Django 1.7

The issue is that if you create a custom field that returns None for db_type(), then it causes crashes due to dereference None to check the startswith().

This worked fine in < Django 1.7 and works fine in upstream."	Bug	new	Uncategorized	1.7	Normal		mysql db_type		Unreviewed	1	0	0	0	0	0
