请教一个bugzilla的问题

安装配置好后
加product user 和 components都没问题
然后我就试了一下提交bug
结果出来了下面的错误：
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, root@nisec and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

apache的日志是这样的：
[Fri Nov 2 17:06:01 2007] [error] [client 192.168.1.122] Premature end of script headers: /usr/local/apache/htdocs/bugzilla/post_bug.cgi

请高手帮我看一下
这是哪出的问题啊，我实在解决不了了，急啊。
非常感谢

解决了
是因为导入了以前的bugzilla的数据库
和后来装的版本不兼容
