Notice from editing Fieldable pane CSS styles

Not sure if this is best in this queue or Fieldable Panels Panes.

Drupal 7.14
Fieldable Panels Panes 7.x-1.0
Panels 7.x-3.2+6-dev
CTools 7.x-1.0

I created a fieldable pane within a panel node, and a few days latter, tried to set the CSS styles on this pane. This was the resulting notice seen in the popup:

Notice: Undefined index: title in panels_renderer_editor->ajax_pane_css() (line 1195 of sites\all\modules\panels\plugins\display_renderers\panels_renderer_editor.class.php).

[void]   panels_renderer_editor->ajax_pane_css('1')
#1369    call_user_func_array(Array, Array)
[void]   panels_ajax_router('editor', 'pane-css', '1', '1')
#516     call_user_func_array('panels_ajax_router', Array)
#21      menu_execute_active_handler()

So in relation to this code in the panels_renderer_editor class

    $pane = &$this->display->content[$pid];
    $subtype = ctools_content_get_subtype($pane->type, $pane->subtype);

    $form_state = array(
      'display' => &$this->display,
      'pane' => &$pane,
      'ajax' => TRUE,
      'title' => t('Configure CSS on !subtype_title', array('!subtype_title' => $subtype['title'])),
    );

The pane dpm() is:

.. (Object) stdClass
    pid (String, 1 characters ) 1
    did (String, 1 characters ) 1
    panel (String, 3 characters ) top
    type (String, 21 characters ) fieldable_panels_pane
    subtype (String, 6 characters ) fpid:3
    shown (String, 1 characters ) 1
    access (Array, 0 elements)
    configuration (Array, 0 elements)
    cache (Array, 0 elements)
    style (Array, 1 element)
        settings (NULL)
    css (Array, 0 elements)
    extras (Array, 0 elements)
    position (String, 1 characters ) 0
    locks (Array, 0 elements)

The subtype return by ctools_content_get_subtype() is an empty array.

Tracing this into ctools_content_get_subtype(), the $panel->subtype passed in is "fpid:3" rather than the real bundle "fieldable_panels_pane", thus breaking the chain.

function fieldable_panels_panes_entity_info() {
  return array(
    'fieldable_panels_pane' => array(
      'bundles' => array(
        'fieldable_panels_pane' => array())));
}

The latest dev version clean up almost all panel notices and warnings, but I'll report the remaining ones that I find. The trace error handler is useful in tracing these :)
