"Is none of" filter for Taxonomy View broken

Hello, I'm building a view of type "Taxonomy."

I have 2 filters, to filter to a specific vocabulary, and to exclude certain terms.

When attempting to view the page, I get the following error

Fatal error: Maximum execution time of 30 seconds exceeded in /.../modules/views/views.module on line 866

When I use the "Is none of" filter for "Taxonomy: Term ID", I get the above error. If change it to "Is one of" for "Taxonomy: Term ID" the error goes away.

Cleared cache, etc. Here's the view. The on the below, the error occurs on the Page and not the Default.

$view = new view;
$view->name = 'taxonomy_site_sections';
$view->description = 'Our site sections, a listing of taxonomy terms.';

$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
