Hi,

I successfully ported Django 1.4.22 to Python 3.5.3.

However, I'm getting a unexpected issue when attempting to fetch a new session key with the
_get_new_session_key() function.

Environment:


Request Method: GET

Traceback:

  344.             return Database.Cursor.execute(self, query, params)

Exception Type: ValueError at /admin/
Exception Value: the query contains a null character

The sql query is:

('SELECT (\x00) AS "a" FROM "django_session" WHERE '
 '"django_session"."session_key" = ?  LIMIT 1')

And the session_key param is: '22fc98168d24a14fe40a3e8956d818ad'


Any idea how to remove the null character (\x00) from the query?

TIA,

Etienne
