Fatal error: Unsupported operand types

In the case when someone doesn't properly set up a webform with components (columns) and tries to look at the table view of said form, one gets a nasty PHP fatality.

Fatal error: Unsupported operand types in /docroot/sites/all/modules/contrib/webform/views/webform.views.inc on line 519

This is due to a zero count of the $new_columns being passed into an array_fill position.

I have updated my codebase with the following which resolves the issue.

      if (!count($new_columns)) {
        drupal_set_message(t('There are no columns to display.'));
      }
      else {
        $style_options['info'] += array_combine($new_columns, array_fill(1, count($new_columns), $style_prototype));
      }

Patch to follow.
