zfs send glitch

[Johannes Totz]

Hi,

zfs send with verbose flag fails for some reason, whereas omitting the
verbose flag works (beware of line breaks):

# zfs send -vRI @120203-2320 backup/alexs-imac/120607-0056 at 120607-0056 |
zfs receive -vun panzer/home/jo/backups/alexs-imac/alexs-imac/120203-2320

And now without verbose flag:

# zfs send -RI @120203-2320 backup/alexs-imac/120607-0056 at 120607-0056 |
zfs receive -vu panzer/home/jo/backups/alexs-imac/alexs-imac/120203-2320

This is on:

FreeBSD XXX 9.0-STABLE FreeBSD 9.0-STABLE #1 r237006: Wed Jun 13

Is this a known glitch? I remember -v used to work fine on this machine
(before I updated it last month).
