Google WMT says 'empty redirect' - but the URLs are live

[experienced]

i check my webmaster tool and found empty redirect by google for the pages which are not redirecting any where and are live urls.

this is a CMS based dynamic site with mod rewrite using htaccess

Can you please suggest me something.

Check the server headers returned when you request the given URL. You may find that a mis-coded script is returning a Redirect status (301, 302, or 303) response with *no* Location header.

I use the Live HTTP Headers add-on for Firefox. There are several other good ones. An HTTP headers checker is basic Webmaster kit.
