I'm not an expert on this code, but the patch looks good and it fixes
some invalid reads for me, so will push in a few days if nobody objects.

Also note that your mailer mangled the patch, so it could not be applied
automatically with 'git am', please fix this in future submissions e.g.
by attaching the patch or sending it with git send-email.
