Fatal error: Call to a set_group_operator() on a non-object in views/includes/view.inc on line 1026

I copied all files and the database of a working drupal 7 installation. I made sure .htaccess and settings.php are fine for my local machine.

Unfortunately neither accessing the page with the browser nor drush are working.

Any ideas?

Accessing the site, I get:

( ! ) Fatal error: Call to a member function set_group_operator() on a non-object in /Users/ernst/Source/php/pluess.li/sites/all/modules/contrib/views/includes/view.inc on line 1026 Call Stack #   Time    Memory  Function    Location 1   0.0011  244032  {main}( )   .../index.php:0 2   0.3487  23720320    menu_execute_active_handler( )  .../index.php:24 3   0.3489  23722112    call_user_func_array:{/Users/ernst/Source/php/pluess.li/includes/menu.inc:527} ( )  .../menu.inc:527 4   0.3489  23722536    views_page( )   .../menu.inc:527 5   0.3824  28116776    view->execute_display( )    .../views.module:600 6   0.4225  31315360    views_plugin_display_page->execute( )   .../view.inc:1385 7   0.4225  31315680    view->build( )  .../views_plugin_display_page.inc:238
