options-permalink.php gives foreach error if no static pages

[MC_incubus]

/wp-admin/options-permalink.php gives a foreach error:

Warning: Invalid argument supplied for foreach() in /home/xxxx/www/www/wp-cvs/wp-admin/admin-functions.php on line 524

Adding a static page makes the error go away.

The problem is that generate_page_rewrite_rules() grabs all the static pages from the DB, but runs foreach on them even if none are returned.
