Using Context Displays with Panels doesn't display views context panes unless exposed filters or sorts are enabled. [#1967362]

Views / Panels / Panelizer / Ctools latest -dev's, this shouldn't be affected by panelizer though.

I have a view with a context pane, which I am using to display the view in a panel page. The first time the page is viewed after clearning the cache the view is displayed correctly. After the first page view I only get non-views panes (or nothing if there are none).

I have attempted to trace this for the view header and it looks like views_content_context_get_output() attaches the view object as $context->output, which then gets returned to views_content_views_header_content_type_render(). At this point it tries to assign $output['header'] to $block->content, but that array element doesn't exist - header is at $output['view']->header, and its neither markup or a renderable array (as far as i can tell).

Strangely, if I add an exposed filter or sort to the view, everything renders correctly. I've managed to replicate the issue using bartik instead of a custom theme, so that rules out a lot of errors.

Here's a backtrace if it helps.

Is the view and context pane you have to replicate this relatively simple? If so, exports might help a lot in tracing this one down.

Replicated on a clean install.

Enabled page manager, panels and views content panes, views_ui and dependencies, all latest -dev versions.

1. Create a view with a context display. Do not add an exposed filter to it, do not add a header to it.

3. Create a custom panel page with a view context related to your view.

4. Add the view context panes to the panel page. Add header, rows & pager context panes.

5. View the page. You should get the error:

Notice: Undefined index: header in views_content_views_header_content_type_render() (line 32 of /home/sam/www/drupal/docroot/sites/all/modules/contrib/ctools/views_content/plugins/content_types/views_header.inc).
Notice: Undefined index: rows in views_content_views_row_content_type_render() (line 54 of /home/sam/www/drupal/docroot/sites/all/modules/contrib/ctools/views_content/plugins/content_types/views_row.inc).
Notice: Undefined index: pager in views_content_views_pager_content_type_render() (line 32 of /home/sam/www/drupal/docroot/sites/all/modules/contrib/ctools/views_content/plugins/content_types/views_pager.inc).

and the view will not render.

6. Go back to the view and add an exposed filter

7. Go back to the panel page again and it works.
