Merged and picked

This one isn't completely fixed, just seen the error again on the cluster

		$content = $this->getContentObject();

		# Use the normal message if there's nothing to display
		if ( $this->firsttime && ( $content === false || $content->isEmpty() ) ) {

But we've specified there is no parameter to getContentObject(), so it defaults to null

protected function getContentObject( $def_content = null ) {

meaning $content can still be null...
