My ~/.ssh files are for the most part even more restrictive

-rw------- 1 jeremy jeremy  446 Mar  2 08:51 config
-rw------- 1 jeremy jeremy 2602 Dec 11 11:47 id_rsa
-rw-r--r-- 1 jeremy jeremy  567 Dec 11 11:47 id_rsa.pub

However I've found the cause of the problem, but not necessarily 
resolved the bug.

For some reason on my journey /etc/ssh/ssh_config had acquired

   UserKnownHostsFile /etc/ssh/ssh_known_hosts

changing to

#   UserKnownHostsFile /etc/ssh/ssh_known_hosts

stops this behaviour.
