 * I’m having some weird issues with a new plugin I am writing. I’m a ruby on rails
   developer and am writing this WP plugin for a friend. Not using anything special
   PHP-wise as far I can I tell but its causing some problems. If anyone can take
   a look at it with me and see if they can find my “bug”, I’d appreciate it.
 * here are the issues:
 * 1) When the plugin is enabled, the RSS/Atom feeds on my site are malformed (they
   have a blank line at the top of the file and the XML declaration is on the 2nd
   line)
 * 2) On my installation of 2.1.3 I don’t see this error but on my friends installation
   of 2.2 he gets this error when trying to login/logout if the plugin is enabled.(
   This seems to happen always if the new HP Blog Printing plugin is activated).

 * Make sure there’s no blank lines before the first `<?php` or after the last `?
   >` tags.
