3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sylvain Munaut <t...@246tnt.com>
(cherry picked from commit f0666b1ac875ff32fe290219b150ec62eebbe10e)
Avoid crashing if the crypto key payload was NULL, as when it was not correctly
allocated and initialized. Also, avoid leaking it.
