ZFS: Invalid SEND/RECV stream still

between 10.0-BETA1 and 11.0-CURRENT.
I've been fighting this battle for a LONG time.  I had hoped(!) that it 
would be solved by the systems being
closer in rev but that didn't happen.

I'd LOVE someone to look at it.

I can provide ssh / root access to both machines.


Error Message:
received 320KB stream in 1 seconds (320KB/sec)
receiving incremental stream of vault/var_at_2013-10-25 into 
zroot/backups/TBH/var_at_2013-10-25
cannot receive incremental stream: invalid backup stream
$

Script:
$ cat backup-TBH-ZFS.sh
#!/bin/sh
DATE=`date "+%Y-%m-%d"`
#DATE2=2013-03-24
DATE2=`date -v "-1d" "+%Y-%m-%d"`
# snap the source
ssh root_at_tbh.lerctr.org zfs snapshot -r vault_at_${DATE}
# zfs copy the source to here.
ssh root_at_tbh.lerctr.org "zfs send  -R -D  -I vault_at_${DATE2} 
vault_at_${DATE} | \
      ssh home.lerctr.org \"zfs recv -F -u -v -d zroot/backups/TBH\""
# make sure we NEVER allow the backup stuff to automount.
/sbin/zfs list -H -t filesystem -r zroot/backups/TBH| \
     awk '{printf "/sbin/zfs set canmount=noauto %s\n",$1}' | sh

What else do y'all need?
