... and no error message logged in the server's log file.

Rsync has historically been hesitent to return error messages from a
server to the client for fear of revealing too much information.  The
2.6.0 and 2.6.1 releases were returning error messages but failing to
log them in the server's log file.  The 2.6.2 release reverts back to
the historical way this was handled.

A better solution for the future would be to log all errors to the
server log and send some/most of them to the user as well.  However,
that will be a complex change, and it has not been worked on yet.

A simpler solution would be to duplicate ALL the messages (the lack of
selectivity make this change easy).  The appended patch should do this,
if you so desire to go that route.
