After a failed zfs receive, zfs list now aborts in make_dataset_handle()
in libzfs.so.2.

# zfs list
Abort trap: 6 (core dumped)

The backtrace is:

#0  0x0000000800fe63cc in kill () from /lib/libc.so.7
#1  0x0000000800fe51cb in abort () from /lib/libc.so.7

Running on:

FreeBSD m8.xxxx.xxx 8.1-RELEASE-p2 FreeBSD 8.1-RELEASE-p2 #0: Sat Jan  8

'zfs scrub' did not fix the error. 'zfs create' and other zfs commands
still work, as do access to the various zfs file systems on this system.

After poking around a bit, I find that in make_dataset_handle()
zhp->zfs_dmustats.dds_type is equal to 0 (and this is the cause of the
abort). Additionally zhp->zfs_dmustats.dds_inconsistent is not TRUE.

Any ideas?  Thanks in advance!

Cheers,

Stef
