Warning: Creating default object from empty value...

[seventhaxis]

I have not seen this issue on my site until tonight. When viewing a specific category of news posts (e.g. Website Updates) I receive the following error at the top of the page:

Warning: Creating default object from empty value in [path]/packages/vbcms/controller/list.php on line 426

Context from the file in question:

425 $recordcount = $collection->getCount();
426 $contentview->contenttypeid = vB_Types::instance()->getContentTypeID("vBCms_Section");
427 $contentview->contentid = $contentview->item_id = $contentview->nodeid = $this->displaysectionid;
428 $contentview = new vB_View_Content('vbcms_content_list');
429 $contentview->package = 'vBCms';
430 $contentview->class = 'Section';
431 $contentview->result_type = $this->result_type;
432 $contentview->rawtitle = $this->title;
433 $contentview->title = $this->title;
434 $contentview->current_page = $current_page;

I took a look at the file but I don't really know anything about PHP. I don't see the error anywhere else on the website and any online searches really don't result in relevant fixes AFAIK. Any and all help is greatly appreciated! If you need any of the files just let me know and I'll throw them up on pastebin or something.
