module doesn't accomadate prefixed table names

I've used the prefix feature for my Drupal database, and all tables are prefixed with dru_. However, when enabling View - Theme, get the following error:

user warning: Table 'web_db.dru_view_theme' doesn't exist query: SELECT v.vid, v.name, v.description, vt.weight, vt.theme, vt.enabled FROM dru_view_view v LEFT JOIN dru_view_theme vt ON v.vid = vt.vid ORDER BY vt.weight, v.name in /opt/lampp/htdocs/web/includes/database.mysql.inc on line 172.
