I think there may be a sequence problem here

Index.php
include_once 'includes/bootstrap.inc';
drupal_page_header();
include_once 'includes/common.inc';

If the cache is turned on drupal_page_header() calls
bootstrap_invoke_all('init');

which calls
     module_load($module);
     module_invoke($module, $op);

So module functions can be called before common.inc is loaded, but only 
if cache is turned on and it's a guest user coming in. And it seems 
quite possible that module writers would use functions that are only 
available *after* common.inc is loaded.
