Call to a member function has_more_records() on a non-object (views_plugin_display.inc on line 2187) causes WSOD [#1113188]

The error occurs in beta3 and the current dev.

It appears that $this->view->query->pager is empty, which is causing the error.

Here is a snippet of a var_dump of $this->view->query

..
["get_count_optimized"]=>
NULL
["pager"] => NULL
["view"] => NULL
["display"] =>NULL
..

Here is the stacktrace of the error:

Can you please export a view, too? This would help to fix the issue.

Additional it might be good to use the latest dev.

I also tried with the current dev (1st of April) and the issue still remains.

See View export attached.

Thanks for the view, btw. For those interested, this is caused because the argument causes the view not to actually execute, but it still has to render and when attempting to render the more link, it tries to ask a pager that never executed if there are more records.

Adding a test to see if the pager exists fixes it; if a pager does not exist at that point, there are obviously not more records.
