apache rewrite出错，请帮忙

[xiu_tong]

我的http.conf配置如下：
<IfModule mod_rewrite.c>
RewriteLog /usr/local/httpd/logs/rewrite.log
#RewriteLogLevel 9
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/mamiai/comm/
RewriteRule ^/bbsview8_(.+)_(.+)\.mamiai$ /bbsview8\.mamiai\?tcd=$1\&seqno=$2 [L]
</IfModule>
出错的日志信息如下：
[size=5]'^/bbsview8_(.+)_(.+)\.mamiai$' to uri '/mamiai/img/menu_080522_on_02.gif'[/size]是怎么出来的？？？？？？？
