dump/restore to 7.4devel giving "[archiver (db)] error returned by PQputline"

Should I expect to be dump/restore from 7.2 to 7.4devel to work
cleanly? Of course it's perfectly OK if the answer is "not surprising
on a devel build" :-) -- just letting people know.

To dump I used:

pg_dump -O -v -h 192.168.50.90 -F c -U logs logs2 -f /mnt/data1/tmp/logs2.dmp

from the new machine with a couple-day-old CVS-tip. The old machine (192.168.50.90)
is running 7.2.

To restore I tried both

pg_restore --no-acl -O -v -U logs -d logs2 < /mnt/data1/tmp/logs2.dmp

which gave me

pg_restore: restoring data for table d_ref
pg_restore: [archiver (db)] error returned by PQputline
pg_restore: *** aborded because of error

and

pg_restore --no-acl -O -v -U logs < /mnt/data1/tmp/logs.dmp | psql logs2 logs

which gave me

ERROR: CopyReadAttribute: Literal carriage return data value
found in input that has newline termination; use \r
CONTEXT: COPY FROM, line 1605109
