If you create a topic without viewing it and the auto-prune kicks in or you trigger a prune from the administration the new topic gets deleted immediately.

This seems to be caused because topic_last_view_time seems to be initialized with 0 when the topic is created.

My quick fix to this problem is to replace in functions_admin.php

	if ($prune_mode == 'viewed')

	{

		$sql_and .= " AND topic_last_view_time < $prune_date";

	}

with:

	if ($prune_mode == 'viewed')

	{

		$sql_and .= " AND topic_last_view_time > 0";

		$sql_and .= " AND topic_last_view_time < $prune_date";

	}
