The user management page fails on searching with role and include disabled users. The problem only appears when search options doesn't include a user name text, but include "include disabled" checkbox and a "role" selected with the dropdown menu.
With this page: /openmrs/admin/users/users.list?name=&role=System+Developer&includeDisabled=on&action=Search.
