This sounds like the problem. I would guess that ZServer is creating a file
in /tmp as root, then changing to uid to nobody, then it tries to write to
the file in /tmp and fails.

This is going to take a little tinkering on my part to get right, probably
I'll delay writing the trigger file until after the suid.

But you should be able to test this by starting ZServer then looking for
/tmp/.select-trigger.<PID> and checking its ownership, and manually fixing
it if you feel like it.

P.S. Actually there is a newer medusa select trigger that may not suffer
from these problems, but I am still having trouble getting it to work under
win32...
