Array being presented to Status report page

Took a while to look into why I was seeing "Array Array" in /admin/reports/status

Looked at the modules/system/system.admin.inc page, inserted:

if (is_array($requirement['title'])) {
  print_r($requirement['title']);
  print_r($requirement['description']);
}

into the theme_status_report() function & got:

Array ( [0] => HTTP request status [1] => HTTP request status ) Array ( [0] => Your system or network configuration does not allow Drupal to access web pages, resulting in reduced functionality. This could be due to your webserver configuration or PHP settings, and should be resolved in order to download information about available updates, fetch aggregator feeds, sign in via OpenID, or use other network-dependent services. [1] => Your system or network configuration does not allow Drupal to access web pages, resulting in reduced functionality. This could be due to your webserver configuration or PHP settings, and should be resolved in order to download information about available updates, fetch aggregator feeds, sign in via OpenID, or use other network-dependent services. If you are certain that Drupal can access web pages but you are still seeing this message, you may add $conf['drupal_http_request_fails'] = FALSE; to the bottom of your settings.php file. )

Which I think comes up in:

sites/all/modules/contrib/linkchecker/linkchecker.install: 'description' => $t('Your system or network configuration does not allow Drupal to access web pages, resulting in reduced functionality. This could be due to your webserver configuration or PHP settings, and should be resolved in order to download information about available updates, fetch aggregator feeds, sign in via OpenID, or use other network-dependent services.'),

but more clearly it disappeared when I disabled this module.

Also saw these with this module:
