We have many private projects and have users individually assigned to the projects. After pulling the latest cvs code (1.0.0rc1), all places which list the users in a project were empty except for 'admin'. Filters, Assign-To drop downs, and in the Manage Project listing of users assigned. From the Manage Projects page, we noticed that the list of available users was properly weeding out the users who were actually already assigned to the project and from the users' pages we could see that they were properly assigned to the project. So, there is an error somewhere in the function either in the query itself or as it's filtering out the results when building the array to pass back. I switched the function back to 19.3's version to get it to work again, else nothing can be assigned to anyone except if logged in as admin.
