[Plugin: PuSHPress] atom:link causing feed to be invalid

I’m using WordPress MU and for some reason when PushPress is activated, this gets added to my sitewide feed:
<atom:link rel=’hub’ href=’http://blogs.courierpostonline.com/?pushpress=hub’/&gt;

This is causing the feed to become invalid and the scripts I use to display the sitewide feed can’t parse. Is there any way to fix?
