I'm receiving this error on my site map page. I'm running Drupal 7.12
Warning: preg_split() expects parameter 2 to be string, array given in _filter_url() (line 1432 of /mnt/www/html/***/docroot/modules/filter/filter.module).
While searching for a solution, several other site map pages showed up in Google with the same error so it doesn't look like it's just me and seems to be tied to the site map module. Thoughts?
