Title:
  Site statistics: Pages - Page not found error when a page's group has
  been deleted in 1.4, followed by an upgrade to 1.8

Status in Mahara ePortfolio:
  In Progress
Status in Mahara 1.8 series:
  In Progress

Bug description:
  If a group has been deleted, the Admin Home/Site Statistics/Pages tab
  (Most Popular Pages) comes up with the error:

  Page not found

  You tried to access a page that does not exist.

  Page with id 0 not found.

  The View construct is trying to load the deleted group but as it is
  deleted, it automatically throws an exception ViewNotFoundException.

  Called in function htdocs/lib/view.php::get_extra_view_info() line
  4124 ($view = new View(0, $v);

  Update: This only occurs when the group was deleted in Mahara 1.4 or
  earlier. After 1.5, the group_delete() function was updated to also
  delete all the group's Pages. And the error on the report page only
  happens in Mahara 1.8, probably due to some change we made in
  View::get_extra_view_info().
