OnOwnerChange still broken in RT-3.0.4

I’m trying to have the new owner of a ticket notified when they are given a
ticket.

Scrip: On Owner Change Notify Owner with template Owner Change

Template Owner Change:
{$RT::WebURL}Ticket/Display.html?id={$Ticket->id}
{$Ticket->Transactions->Next->Content()}

No email is sent when a ticket is given from one user to another. It’s not very
complicated; seems like it should work. Any ideas?

RT 3.0.4, Mac OS X 10.2.6, Apache 1.3.27, modperl 1.27, perl 5.8.0, mysql 4.0.12
