While EGLIBC[0] was kind enough not to crash here, you shouldn't rely on
its forgiveness. Trying to format a NULL with %s is wrong.
[0] From documentation: "If you accidentally pass a null pointer as the
argument for a `%s' conversion, the GNU library prints it as `(null)'.
We think this is more useful than crashing. But it's not good practice
to pass a null argument intentionally."
