Error after activating the module

After activating the module and rebuilding privileges I get this error message in a ping rectangle on all the site:

user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DISTINCT(node.nid), node_revisions.title AS node_revisions_title, node_rev' at line 1 query: SELECT DISTINCT(node.nid) AS DISTINCT(node.nid), node_revisions.title AS node_revisions_title, node_revisions.nid AS node_revisions_nid, node_revisions.timestamp AS node_revisions_timestamp, history_user.timestamp AS history_user_timestamp, history_user.nid AS history_user_nid, node.created AS node_created, node.changed AS node_changed FROM node node LEFT JOIN node_revisions node_revisions ON node.vid = node_revisions.vid LEFT JOIN history history_user ON node.nid = history_user.nid AND history_user.uid = 1 ORDER BY node_revisions_timestamp DESC LIMIT 0, 7 in /var/www/drupal/modules/views/includes/view.inc on line 725.

After disabling the node the message disappears (ufff!)

Thanks for your attention.
