+
+The SQL being generated by Django is correct:
+
+{{{
+#!python
+>>> Item.objects.dates('created', 'day').extra(select={'a': 1}).query.as_sql()
+('SELECT DISTINCT (1) AS "a", django_date_trunc("day", "sqlite3_dates_item"."created") FROM "sqlite3_dates_item" ORDER BY 1 ASC', ())
+}}}
+
+The problem has been tracked down to a bug in SQLite in version older than 3.3.6.
