Every website starts with a leading space before the header like: ' <!DOCTYPE html PUBLIC ...' This is not a problem for browsers, but for RSS/ATOM-Feed readers, while browsing the Feeds in 'RecentChanges'.
Check for whitespace before the <?php tag in LocalSettings.php; that's often where such things creep in. No such space for me using up-to-the-minute SVN trunk.
