[news.eclipse.technology.equinox] [p2] Update site category not working

[Eric Rizzo <eclipse-bugs@xxxxxxxxxxxx>]

Can anyone explain why the following update site, when added to the 
Install New Software wizard, tells me "There are no categorized items"?

<site>
<description url="http://www.rizzoweb.com/Eclipse/updatesite";>
      Eric Rizzo's misc. plug-ins.

<feature 
url="features/org.eclipse.community.feature_0.2.0.200908092301.jar" 
id="org.eclipse.community.feature" version="0.2.0.200908092301">
<category name="org.eclipse.community"/>
</feature>
<category-def name="org.eclipse.community" label="Eclipse Community"/>
</site>

The feature does show up if I un-check the "Group by category" option, 
but why is it not recognizing the category?
