#3 may be the problem.  Some RERR_PARTIAL error messages contain that
sequence, for example, 'rename foo -> "bar": Operation not permitted'.

Yes.  If rsync exits with RERR_PARTIAL without printing a specific
message about the problem to stderr, it's a bug.

I would suggest sending stdout and stderr to separate files, like this:

rsync ... >rsync.out 2>rsync.err

Then look at rsync.err.  It should have the relevant errors and nothing
else.  If it is empty, then something deeper is wrong and it may be
helpful to strace rsync.
