tarsnap: Error exit delayed from previous errors.
It's always the same directories and they happen to be toward the end of the archive.
As far as I can tell, there's nothing unusual about any of those directories:
1088000236 973 drwxr-xr-x 2 cva cva 0 6 "Jan 22 14:57:08 2011" "Jan 22 14:57:08 2011" "Jan 22 14:57:08 2011" "Jan 22 14:57:08 2011" 131072 4 0 /home/cva/src/ring.git/objects/15
And they've backed up in the past.
This is tarsnap 1.0.28 on Freebsd 8.2-RC2 on a ZFS filesystem.
