    That can't be 2.6.6 because 2.6.6 doesn't have an error message of that
    format.  In 2.6.6, the old "malformed address" error now outputs as
    "error matching address" and includes the gai_strerror() text after a
    colon.  A new error in 2.6.6 that does include the string "malformed
    address" would have also included the gai_strerror() text after a colon.
    Thus, that's still the old rsync running.  Perhaps it didn't really get
    stopped?  Or perhaps it is running via inetd?

Given how often rsync versions change and how much functionality goes
into each new one (yay!), I wonder if it might not be such a bad idea
to have the rsync version embedded in every error message?  With most
programs, it's likely that the user knows at least something about the
version they're running, but since rsync is almost always run with one
of the instantiations remote, it might make debugging easier if the
message was explicit...
