4.6版的论坛发帖的问题

新手呵呵,装的是4.6版,论坛设置好之后,发帖总是出现类似下面的错误:
sprintf(): Too few arguments in /var/www/html/krsna/engine/includes/database.inc on line 147.
Query was empty query: in /var/www/html/krsna/engine/includes/database.mysql.inc on line 66.
...
不过帖子还是发出去了,论坛其他功能都还正常,修改帖子也没问题,报告了bug,不过还没人回复,只好问这里的各位大老是否也遇到过,如何解决呢?
