When I follow the directions for "Theming the maintenance page" (http://drupal.org/node/195435) and set $conf['maintenance_theme'] = 'zen'; in my settings.php, then set my site 'offline' through the maintenance admin page, everything works fine.

But when I turn my database off to simulate DB failure (as suggested in the doc), I get a bunch of SQL warnings, like this:
Warning: mysql_real_escape_string() expects parameter 2 to be resource, null given in /x/x/x/includes/database.mysql.inc on line 321

I can't tell for sure, but is Zen creating these? Or is it something else I did? I haven't hacked anything.

BTW, if I set $conf['maintenance_theme'] = 'minnelli'; in settings.php, no SQL warnings appear.

I'm seeing this behaviour too, definitely a problem with Zen.
As a test, i copied maintenance.tpl.php into bluemarine and no php warnings showed up at the top of the maintenance page with that theme.

in the hook_theme() function for zen, theme is trying to query the database, resulting in php warnings on the maintenance page when the database is down.
provided patch to check if db is active or maintenance page is up.

Sweet! I love patches. I'll review this weekend if no others get to it first. :-)

Marked #317409: not considering possible missing database connection: drupal_get_path('theme', 'zen') as a duplicate of this one since this one contains a patch.

The patch in #2 doesn't work. With it, I get a multiple warnings when rebuilding the theme registry.

I've committed a simpler patch.
