Hello Paul,
This bug has already been fixed upstream, but not yet released. You
can apply attached patch to fix the problem.
See also: https://alioth.debian.org/tracker/?func=detail&aid=311595
(tab "Attachments").
To reproduce the problem:
$ cat > /tmp/config <<"EOF"
> Host foo
> UserKnownHostsFile "/dev/null"
> UserKnownHostsFile "/dev/null"
> EOF
$ ssh -F/tmp/config <TAB>
$ ssh -F/tmp/config bash: /dev/null: Permission denied
...
After the patch, completion should succeed without any error "Permission
denied":
$ ssh -F/tmp/config <TAB>
...
Regards,
Freddy Vulto
