[Radiant] Anyone else having an issue when adding a new RSS feed using external_rss_feed extension?

[Jared Blitzstein]

I installed the extension and when I click "New Feed" from the admin  
layout, I get the following stack. I assume "valid" is a reserved  
keyword and is causing the error. Anyone else run into this?

valid? is defined by ActiveRecord
Extracted source (around line #10):

7:   <div class="form-area">
8:     <p class="title">
9:       <label for="external_rss_feed_name">Name</label>
10:       <%= text_field "external_rss_feed", "name", :class =>  
'textbox', :maxlength => 100 %>
11:     </p>
12:     <p class="title">
13:       <label for="external_rss_feed_url">URL</label>
