You can also get to this error page by doing the following:
Visiting /wp-admin/plugins.php on a site where Akismet is NOT activated. The link to the configuration page is still there in the description, but following it takes you to a Permission Denied page.
Perhaps the best fix is to remove the link from that section, and put it with the Action Links in the other column, where it can be controlled through plugin code via filters, not show up on the network admin, and only be present when the plugin is active.
