I solved the problem by putting the following lines in the views_fusion_views_query_alter() function:

317       //set page type to table view, so that the fields get built
318       $fuse_view->page = 1;
319       $fuse_view->page_type = 'table';
320
321       // SD: Added following lines to suppress error
322       if (!$fuse_view->filter) {
323         $fuse_view->filter = array();
324       }
325       if (!$fuse_view->argument) {
326         $fuse_view->argument = array();
327       }
328       if (!$fuse_view->sort) {
329         $fuse_view->sort = array();
330       }
331       if (!$fuse_view->field) {
332         $fuse_view->field = array();
333       }
334       // END SD
335       // call this hook for the fused view and set the query object reference
336       $info = _views_build_query($fuse_view, $view->args, views_get_filter_values());

Not sure if something I did wrong is causing these errors or not. Looking for feedback before I roll a patch.
