When my site loads, it usually throws a few warnings and consequently I get sent to line 656 of common.inc, which calls filter_xss as of Drupal 6.21. The trouble is that filter_xss is not defined at that point in the bootstrap sequence, so when I load any page, I get a whitescreen with the error "Fatal error: Call to undefined function filter_xss() in /var/www/dev.treepeople.org/includes/common.inc on line 656".
An easy fix is just to create a filter_xss* function in common.inc, but this seems redundant. Any ideas? If filter_xss* is the best solution, I can submit the patch.
