Problem with data base tables with prefix (p.e. drupal_ )

There is a bug easy to solve. In the line 106 of the module file webform_rules.rules.inc the actual code is:

$result = db_query("SELECT nid, title FROM node WHERE type = :type", array(

and I think must to be

$result = db_query("SELECT nid, title FROM {node} WHERE type = :type", array(

If the intallation of your Drupal data base was made with table prefix (i.e. drupal_) with the actual version you will have some errors.
