Category RSS feeds not validating

I am trying to roll my category rss feeds through Feedbruner.
However, when I do I get validation errors.

Feedvalidator.org is spitting this back at me:

Sorry
This feed does not validate.

line 2, column 0: Undefined root element: script [help]

<script type="text/javascript">window.location="/wp-content/plugins/wp-passw ...
line 2, column 106: XML parsing error: <unknown>:2:106: not well-formed (invalid token) [help]

... s/wp-password/login.php?err=&destination=/category/apd/feed/";</script>

In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendation.

Feeds should not be served with the “text/html” media type [help]

<script type="text/javascript">window.location="/wp-content/plugins/wp-password/login.php?err=&destination=/category/apd/feed/";</script>

<noscript>An automatic redirect has failed.  You should have been redirected to <a href="/wp-content/plugins/wp-password/login.php?err=&destination=/category/apd/feed/">this url</a>.</noscript>

Might someone know what is going on?
Point me in the right direction?

Thanks,
Bert
