You are missing rsync's output to stderr. There should be at a minimum
"rsync error: error in rsync protocol data stream (code 12)", and
probably a preceding error message that would give us an idea of what
the problem is. Adjust your setup so you can capture the stderr, or if
all else fails, run the rsync manually.

OK, then your problem is something other than the compression
false-match issue we were discussing.
