"Yes" is the default, so you have to explicitly write "use chroot = no".
(Sorry, I should have mentioned that.)

Weird!  You might check if the daemon is logging to syslog
(/var/log/messages) for some reason, as it will fall back to syslog if
it fails to open the log file, though I don't see why it would fail now
that you have fixed the permissions.  If that doesn't reveal anything,
try running the daemon under strace by passing
--rsync-path='strace -f -o ~/rsync.strace rsync' to the client.
