Cant preview posts with custom user role.

Hello,
I encounter a bug when I activate this plugin and then later try to preview a regular post as user with a custom user role.

When user assigned to this role the preview of a post delivers a 404.

I am using this code to add the new user role, if you need to reproduce.

$new_role = get_role('editor');
$caps = $new_role->capabilities;
$caps['NextGEN Gallery overview'] = '1';
$caps['NextGEN Use TinyMCE'] = '1';
$caps['NextGEN Upload images'] = '1';
$caps['NextGEN Manage gallery'] = '1';
$caps['NextGEN Manage tags'] = '1';
$caps['NextGEN Manage others gallery'] = '1';
$caps['NextGEN Edit album'] = '1';
$caps['NextGEN Change style'] = '1';
$caps['NextGEN Change options'] = '1';
$caps['manage_polls'] = '1';
$caps['uninstall_polls'] = '1';
$caps['edit_theme_options'] = '1';
$caps['aller_fabriken_edit'] = '1';
$caps['gform_full_access'] = '1';
$caps['edit_tribe_event'] = '1';
$caps['read_tribe_event'] = '1';
$caps['delete_tribe_event'] = '1';
$caps['delete_tribe_events'] = '1';
$caps['edit_tribe_events'] = '1';
$caps['edit_others_tribe_events'] = '1';
$caps['delete_others_tribe_events'] = '1';
$caps['publish_tribe_events'] = '1';
$caps['edit_published_tribe_events'] = '1';
$caps['delete_published_tribe_events'] = '1';
$caps['delete_private_tribe_events'] = '1';
$caps['edit_private_tribe_events'] = '1';
$caps['read_private_tribe_events'] = '1';
$caps['edit_tribe_venue'] = '1';
$caps['read_tribe_venue'] = '1';
$caps['delete_tribe_venue'] = '1';
$caps['delete_tribe_venues'] = '1';
$caps['edit_tribe_venues'] = '1';
$caps['edit_others_tribe_venues'] = '1';
$caps['delete_others_tribe_venues'] = '1';
$caps['publish_tribe_venues'] = '1';
$caps['edit_published_tribe_venues'] = '1';
$caps['delete_published_tribe_venues'] = '1';
$caps['delete_private_tribe_venues'] = '1';
$caps['edit_private_tribe_venues'] = '1';
$caps['read_private_tribe_venues'] = '1';
$caps['edit_tribe_organizer'] = '1';
$caps['read_tribe_organizer'] = '1';
$caps['delete_tribe_organizer'] = '1';
$caps['delete_tribe_organizers'] = '1';
$caps['edit_tribe_organizers'] = '1';
$caps['edit_others_tribe_organizers'] = '1';
$caps['delete_others_tribe_organizers'] = '1';
$caps['publish_tribe_organizers'] = '1';
$caps['edit_published_tribe_organizers'] = '1';
$caps['delete_published_tribe_organizers'] = '1';
$caps['delete_private_tribe_organizers'] = '1';
$caps['edit_private_tribe_organizers'] = '1';
$caps['read_private_tribe_organizers'] = '1';

$factory_editor = add_role('factory_editor', 'factory_editor', $caps);
