9.1.4: pg_restore: couldn't uncompress data?

This one is concerning.  Trying to restore a backup from one system to
another, and got this:

pg_restore: restoring data for table "userid"
pg_restore: restoring data for table "values"
pg_restore: [compress_io] could not uncompress data: (null)
pg_restore: *** aborted because of error
[lrosenman@bpsandbox-db2 ~]$ ls -l db*
-rw-rw-r-- 1 lrosenman blueprint 10838183690 Jul 23 17:58
db.backup.2012_07_21T062258
[lrosenman@bpsandbox-db2 ~]$

The file is the same size on both systems, and was transferred with scp.

Any ideas why I would see this?
