12909	Exceptions raised in response middleware don't invoke site 500/404 handlers.	jhovanny	nobody	"If there is an error connecting to the session database, the session middleware throws an Exception that's visible regardless of the DEBUG setting. The stack trace appears in a blank page (non-conforming to the standard debug template). To reproduce this ticket, drop the django_session table and try to login to any django application. The expected behavior is not to show a stack trace when DEBUG=False
