Tested and experiencing the bug with no plugins on both WP 2.2.1 and WPMU 1.2.3. Only happens if wp-blog-header.php is inlcuded in the config.php for bbPress.

Might it be some server setting?

Currently experiencing on three different machines, very similar setups though. I will test this on a different machine/setup tonight.
