I'm upgrading a Drupal 4.7.2 site to 5.7, I've done this several times before but this is the first time I've run into this particular issue. Paging has stopped working. I already posted this as a support request at http://drupal.org/node/258014, but there were no responses so I thought I'd try here to see if anyone else has come across this. Here's a drupalbin of my debugging attempts, http://drupalbin.com/1704.
