Calendar.views.inc breaks other views

Very much similar to the issue reported here for the date module (http://drupal.org/node/490110), some of the code in calendar.views.inc is preventing my other, simple views that are not related to calendar or date to function properly under the standard theme. I can see the menu item for the view, and when I click on it, there's no results nor the title of the page is set properly for the menu entry.

I had to comment out all the lines of (lines 120, 143, 162 to be precise):

'theme' => 'views_view',

for those views to function again.

Hope this helps someone.
