user warning: The used SELECT statements have a different number of columns query:

Hi,
Fresh open atrium beta8 install, updated views to 3.alpha3.
Needed to change the following, because of this error:
PHP Fatal error: Call to undefined method views_plugin_display_block::get_cache_plugin() in /profiles/openatrium/modules/atrium_features/atrium_activity/atrium_activity.views.inc on line 97

Patch http://drupal.org/files/issues/nodecomment.module.cache_.patch needed because of same issue as http://drupal.org/node/908258
   $cache = !empty($view->live_preview) ? FALSE : $view->display_handler->get_plugin('cache');

But now I got following errors:
