Leopard, home on NFS, and Trash

[Gregory Seidman]

I keep my mother's home directory on a RAID running on a Linux server, and
this has been working beautifully for years under Tiger. Her logic board
died and she got a new machine; of course, it came with Leopard installed.

With a little bit of looking around I discovered the Directory Utility. I
set up her home directory's NFS mount, fixed her UID and GID to match what
it had been, made sure she owned the mountpoint, etc. When she logs in her
home directory mounts automatically and everything works great. Well,
almost.

The Finder doesn't see anything in the Trash, even though her .Trash
directory is full of stuff. Dragging a file to the Trash warns that it will
be deleted immediately instead of being moved to the Trash and, indeed,
that's what happened. I moved .Trash aside, restarted the Finder, and it
correctly created a new .Trash directory. The problem with nothing
appearing in it (even when I move something in from the commandline) and
the warning (and behavior) about deleting immediately remains, multiple
Finder restarts notwithstanding.

Any ideas on how to fix that?
