It seems that version 3.0.6-4.el5 of rsync that was made available from 
the sl-security repo yesterday is broken.  In my usage:

rsync -rlHptS --delete --rsh=ssh <directory> <machine>:<directory>

ssh is being invoked with no arguments.  This is, obviously, causing it 
to fail.

Has anyone else seen this?

Thanks.
