The same dump was restored w/o problems with both pg_restore 7.3.8 and
7.4.6.

Dump header, produced with pg_restore 7.3.8 is:
;
; Archive created at Wed Jul 7 04:03:02 2004
; dbname: XXXX
; TOC Entries: 1982
; Compression: -1
; Dump Version: 1.5-7
; Format: CUSTOM
; Integer: 4 bytes
; Offset: 4 bytes

Seems to be caused by a recent patch:
http://developer.postgresql.org/cvsweb.cgi/pgsql/src/bin/pg_dump/pg_backup_a
rchiver.c#rev1.101

Workaround is to use pg_restore -O
