creating gallery.access_url on multicontext site breaks manager

Hi all,

I have a multicontext site running Revo 2.6, and was creating gallery settings for Gallery 1.5.2.

If I create the setting gallery.access_url (even if it's blank), the manager breaks. I get a blank page screen (though the resource browser/navigation are still viewable) for most thing (ie package management, etc) but if I view a resource I can see part of the template variables section.

However, the photo gallery displays correctly when I set correct value in gallery.access.url (I then have to delete it before exiting the system settings to make the manager work again). I only get one error in the error log:

[2013-01-30 12:43:04] (ERROR @ /modx/assets/components/gallery/connector.php) Error caching action map mgr/actions

Revo 2.6
PHP Version 5.2.17
MySQL 5.5.29

Anyone have a suggestion?
