User creation/display oddity

I’ve just set up a fresh install of RT 2.0.13 with a mysql backend. I’m using
Mozilla 1.0RC1 as the client. OS is FreeBSD 4.5-STABLE. I’ve successfully
created two users and can see them if I look at the mysql database directly.
Here’s one of them (info changed, obviously):

| 7 | user | password-deleted | NULL | NULL | user@oceanwave.com | NULL
| Oceanwave Consulting, Inc. | 1 | User’s Name | NULL | NULL | NULL
| NULL | NULL | NULL | NULL | NULL | user | NULL | NULL | NULL | NULL
| 21 Old Town Rd. | NULL | Beverly | MA | 01915 | USA | 3 |
2002-05-10 00:25:28 | 3 | 2002-05-10 00:25:30 | 0 |

When I try to add users to groups or search for users or assign tickets to
users, though, the list of users (with matching criteria) are never shown.
The search doesn’t come back without any matches, since that results in the
text: “No users matching search criteria found.” Instead I get no error
message and no displayed users.

Oddly, the users can log in and take tickets just fine. The only user that
anything can be given to, though, is Nobody:

| 2 | Nobody | NO-PASSWORD | Do not delete or modify this user. It is
integral to RT’s internal data structures | NULL | NULL | NULL | NULL |
2 | Nobody in particular | NULL | NULL | NULL | NULL | NULL | NULL | NULL
| NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL
| NULL | 1 | 2002-05-09 22:42:47 | 1 | 2002-05-09 22:42:47 | 0 |

Anyone have any clues why?
