What steps will reproduce the problem? 1. Had compaints that users are not sorted in drop-downs, e.g. in Permissions dialog.

What is the expected output? What do you see instead? Users are in 'id' order.

What version of the product are you using? On what operating system? This is against 2.5.19 but also seems applicable to 2.5.21 and 2.5.22

Please provide PHP error log and any additional information below. I have made this a tentative patch as I am not able to ascertain whether any other part of the the system assumes/expects/requires the result of the getAllUsers() call to be in 'id' order.
