"Notice: Undefined variable: data" upon enabling of Views module

Not too terribly important, but I admit I was a bit disconcerted to see a red error box when enabling the Views module.
The following message appears once upon enabling the views module:

Notice: Undefined variable: data in civicrm_views_plugins() (line 6917 of /home/jesse/projects/VEDA/app/veda_install/modules/contrib/civicrm/drupal/modules/views/civicrm.views.inc).

It looks like if the Calendar module is not enabled, this hook tries to return the $data array that's not defined.

putting: $data = array(); before the if statement clears up the error. Note this only happens the first time the module is loaded.

To reproduce, uninstall views, then re-enable it. Here's a drush command sequence to accomplish this:
drush dis views views_ui --yes; drush pm-uninstall views_ui --yes; drush pm-uninstall views --yes; drush en views views_ui --yes;
