$FULLME gets set to NULL in certain places in initialise_fullme() and initialise_fullme_cli()

// Probably some weird external script
$SCRIPT = $FULLSCRIPT = $FULLME = $ME = null; ...
if (strpos($topfile, $dirroot) !== 0) {
// Probably some weird external script
$SCRIPT = $FULLSCRIPT = $FULLME = $ME = null;
} else {
$relativefile = substr($topfile, strlen($dirroot));
$relativefile = str_replace('
', '/', $relativefile);
// Win fix
$SCRIPT = $FULLSCRIPT = $relativefile;
$FULLME = $ME = null;
}

This happens on forum cron when subscriptions send to bad email address etc.
