The $rdf_namespaces variable is not found in the default maintenance-page.tpl, but Zen has it and it causes PHP notices when the maintenance page is viewed:

Notice: Undefined variable: rdf_namespaces in include() (line 17 of sites/all/themes/zen/templates/maintenance-page.tpl.php).

This variable needs to be removed.
